There is no sound playback device Windows 7. What to do if the sound on the laptop disappears

If you compare a computer and a laptop, it turns out that the latter device is more problematic. Therefore, users often prefer to have a PC, despite the mobility of a laptop. What are the problems with the laptop?

The fact is that a laptop is a device that is difficult to take apart. If in a computer you can separate the video card, sound card or RAM from the motherboard, then in a laptop most of the components are built into the motherboard. Therefore, if any problems occur with one piece of hardware, the entire system may suffer. If the entire system suffers, then replacing it will be very expensive. But with a computer in this regard, things are simpler. The video card is broken - we take it out and replace it with a new one. It's the same with the sound card. But what to do if the sound on the laptop disappears?

Causes

There are quite a few reasons for this problem. Most of them can be solved programmatically by correcting some settings or updating drivers. But if the problem lies precisely in the sound card, then more serious troubles may arise.

If you notice that there is no sound on your laptop, what should you do first? Do not rush to grab the device and take it to the service center. There can be many reasons for this breakdown. Some can be solved on your own in just a few minutes. Among the main reasons are:

• problems with the playback device;
• reset volume settings;
• driver failure;
• sound manager settings;
• activating the sound card in BIOS;
• audio and video codecs.

Playback device

You can determine why the sound on your laptop disappears without the help of specialists. To do this, just take a close look at the devices that reproduce sound. For example, headphones served as such a device. They often encounter problems that are difficult to solve. Most of them result in the headset being sent back to the store, to a service center, or even thrown into the trash.

If you were listening to music on your laptop, turn them off and listen to whether the laptop's speaker plays the melody. If everything is fine, then most likely there is a problem with the headphones. But such a check does not guarantee that the headset is really broken. It happens that you used headphones in the evening, the next day you turned on your laptop, but it makes no sound. You turn off the headset, but the speakers don't make any sound either. As practice shows, this is a common hardware failure. You need to connect and disconnect the headphones several times, and the sound will appear.

Often users use speakers instead of headphones. Acoustics also does not last forever; problems occur with it that are difficult to properly assess at first. The speakers may fail; their plug or power cord may be damaged. In this case, it is better to check them on another device. This is more likely to show the whole situation. Perhaps it was a malfunction of the acoustics that led to the loss of sound on the laptop.

And finally, no matter how stupid it may sound, in case of such a breakdown it is important to check the sockets and plugs. Perhaps you forgot to connect the speakers to the outlet or turn them on. The wire that connects to the laptop may have been damaged. All this can also cause the problem described.

Volume Settings

Not all PC users can be called experienced. Some people's knowledge is limited only to starting the system and logging into the browser. Therefore, it is important for such people to be attentive to all the processes that occur while they are using a laptop.

If you notice that the sound on your laptop has suddenly disappeared (with Windows or another operating system - it doesn’t matter), take a closer look at the tray (lower right corner of the screen). This area usually displays the date and time, there is an input language setting, wireless network, power supply, etc. There is also a special sound icon.

It happens that by pressing some key combination you could lower the volume or mute it completely. In this case, you need to click on the icon in the tray and look: if there is a cross on it, then the sound is muted, if not, perhaps the volume scale is turned to the left, so the sound is very quiet, and therefore it seems that it has disappeared.

Mixer

But that's not all. If you right-click on the sound icon, the usual volume scale will open, and if you use LMB, you can select several settings. First, go to the mixer.

This option is also important in the sound settings. The mixer indicates several programs on the laptop that use sound. For example, Skype, a browser, system sounds, etc. can be displayed here. Each program has its own volume scale. Perhaps the browser volume was turned off, so when you turned on a video on the Internet, you thought that the sound on your Windows 7 laptop was missing.

Next you need to check the installed playback device. To do this, LMB click on the tray icon and select the appropriate section. The sound settings will open. The first tab will indicate the playback device. There may be several of them. You need to take a closer look at the names. It happens that one speaker system is installed instead of another.

It is important to set everything up correctly. If you can’t determine which device you need, try LMB-clicking on each of them and turning them on one by one. When you select the one you want, you will notice that the volume scale activates next to the name.

Alternatively, you can also try running the internal troubleshooting service. To do this, left-click on the tray icon again. Find the line “Detect sound problems.” The system will automatically launch diagnostics and indicate possible solutions as errors are found. Sometimes it will automatically fix the problem.

System Drivers

If all the above solutions do not work, what should I do? There is a possibility that the problem lies in the drivers. Let's say you notice that there is no sound on your laptop. How to fix this problem? You need to check that the drivers are working correctly. To do this, go to the “Start” menu, in the right column we find the “Control Panel” section. A new window will open in which you will need to find the “Device Manager” section. All connected devices to the system will appear in a new dialog box. Here you need to find the line that relates to the sound. Most often it is called “Sound, video and gaming devices”.

Click on the plus sign next to this name. Another list will open, which will indicate all the devices belonging to this category. You need to look at them carefully. You may notice that one of them has an exclamation mark or a red X next to it. This means that the device has failed.

If something really happened to the drivers, you need to click on the faulty device LMB and select “Disable” and “Enable” again. If this doesn't help, click Update Drivers. If this does not give any result, you can try removing this device from the system. Uninstalling may work, but to do this you will have to install new drivers. If there are no installation disks left, look for the necessary files on the Internet. Most of them are on the official website of the laptop manufacturer.

If you don’t notice any exclamation marks or crosses, see if there is an “Unknown Device” in the list. There is a possibility that the system was unable to determine the device model and install drivers for it, so you will need to do this yourself.

Helper program

To cope with the drivers and fix the problem that the sound on the laptop has disappeared (“Windows 10” can especially “please” the user with this and other problems), you can install a special program. It will definitely be useful for restoring other devices in the future. The Driver Booster utility can be installed for free. It quickly checks and finds the necessary drivers for all system devices. The user only needs to give his consent to download the relevant files.

Problems with the sound manager

Above we looked at the sound settings in the system itself. But there is another service that helps with deeper device configuration. This program is installed along with the sound drivers. In almost all systems it is called Realtek High Definition Audio. The utility helps you set the optimal settings if there are any problems with the sound.

To do this, go to the “Control Panel”, as described above. Then you need to select a viewing option. It is in the upper right corner. You can choose to display large or small icons, and also select the “Category” section. It’s the last option that you need to click. All elements in the dialog box will be rearranged. You need to find “Hardware and Sound” and select the very last item.

The built-in audio configuration service will open. It needs to be examined carefully. Depending on your requirements, you can customize the sound for yourself.

BIOS settings

Also, if there is no sound on a Windows laptop, what should you do? Of course, BIOS is one of the last options that could fail. However, there are also cases when the laptop turns off the sound card, and you need to turn it on yourself.

To go to the BIOS, you need to turn off the computer and press the Del or F2 button while it starts. This is a common option for how to get to this menu. But he is not always like that. Therefore, check in advance on the Internet which combination of buttons your particular laptop model supports.

The BIOS version may also differ depending on the firmware. Therefore, you will have to “travel” through the entire menu. You need to find the Audio or Advanced section. There you will notice the name of the sound card. Most often it sounds like High Definition Audio. Opposite the line will be written Disabled if the option is disabled and Enabled if it is enabled. Select the desired item and do not forget to save the changes. Below is a key that must be pressed for the changes to take effect.

Working with codecs

It happens that the sound disappears on the laptop while playing a track or movie. At the same time, you hear everything. Most likely you are faced with codecs. What do we have to do?

• remove existing codecs;
• reboot the laptop;
• download and install new codecs.

Removing codecs will depend on what software you are using. Therefore, it is difficult to describe the algorithm of actions here. It can be different for each existing program. Usually, when starting a movie, you need to go to the player menu, and there find the “Filters” item. It is there that the codecs are indicated. You can also use a special program that allows you to manage codecs.

Windows 10

It happens that the sound disappears on a laptop with Windows 10 on board. In this case, there are no fundamental differences in fixing this problem relative to other systems. You also need to first check the playback device, then examine the sound settings, both system and software. You'll have to work with drivers and BIOS.

Solution

If none of the above works for you, and there is still no sound, you can start blaming the sound card. If your laptop has problems with it, then you will have to take it in for repair or buy an external device.

If you decide to renovate, there is a chance that it will take you a lot of time and money. Therefore, many people choose to buy an external sound card. It looks like a regular flash drive that has microphone and headphone jacks. Of course, the ideal option is to purchase a “native” sound card, but if this is not possible, try to find the highest quality model.

There is one drawback to such a solution. It is difficult to understand for sure that the problem is in the sound card. The sound problems may be caused by viruses or system clogs. Therefore, many people finally recommend reinstalling the operating system. There is a possibility that some system files have been damaged, which will be restored when the OS is installed. If this option does not help, then the problem is definitely in the sound card.

If you have lost sound on your laptop, then there is no need to panic: in the vast majority of cases, the problem can be solved by simply changing the system parameters. The only thing you should be concerned about is damage to the speakers and sound card, but these problems can be fixed fairly quickly.

Checking the volume

Before you start reinstalling the driver and other serious methods, check whether the sound on the laptop is turned on at all. Sometimes users accidentally turn off their speakers and start to panic prematurely without checking basic things.

This method often solves the problem when you hear system sounds, but, for example, in a browser or a separate application you are greeted by silence. The method works on all versions - from XP to Windows 8 and Windows 10.

You can adjust the volume using hot keys. For example, on ASUS laptops the combinations Fn+F10 (turn off), Fn+F11 (decrease) and Fn+F12 (increase) are responsible for this function.

If there is no sound on a particular site, then check whether the volume is turned up on it. All built-in audio and video players have their own control, don't forget about it.

No volume icon

If the sound icon has disappeared from the tray, you can get it back through the taskbar properties:

Also, go to the "Turn system icons on or off" link. Find the “Volume” item and set it to “On”.

If the icon still sometimes disappears (for example, after a reboot), then try to fix the problem with Microsoft Fix it 50229 (works on Vista and Windows 7). The small utility creates a restore point after launch and then fixes errors with system icons. The same steps can be performed manually through the registry editor, but it is better to use automated tools so as not to accidentally disrupt the system.

Windows Audio service is disabled

In some cases, the sound on a laptop does not work due to the fact that someone accidentally or intentionally disabled the Windows Audio service. To eliminate this system flaw:

1. Press "Win+R".
2. Write “services.msc” in the window and click “OK”.
3. Find the Windows Audio service and make sure that its status in the “Status” field is “Running” (“Running”). The startup type must be automatic.

If the settings are incorrect, double-click the service. A window for making changes will open: select automatic startup type and click “Run” (if the service is stopped).

On Windows 10 (Seven and Eight also have this option), you can check the status of the service through the task manager. Call it with the combination Ctrl+Shift+Esc or any other way and go to the “Services” tab. Follow the steps above.

Driver failure

If the speaker volume is set to an acceptable level, the Windows Audio service is turned on, but the sound on the laptop still does not work, then you need to check the sound card drivers.

You can install drivers manually by first downloading them from the laptop manufacturer's website. It is important to download software for your specific laptop model to avoid compatibility issues. If the driver corruption is due to an incorrect update, then you need to run a rollback procedure.

Open the properties of the sound card and on the "Driver" tab, click "Roll Back". After confirming the operation, the previous version of the software will be restored.

Sound card disabled

What should you do if there is no sound on your laptop and none of the methods described above helped? Launch BIOS and see if the sound card is enabled. The path to the hardware is different in different BIOS versions and firmwares, but the general order is something like this:

If near an item with a name like “Onboard Sound”, “Hight Definition Audio”, etc. The value is “Disabled”, which means the sound card is disabled. Change the value to “Enabled” to make the device work.

Other reasons

Concluding the review of the main reasons for loss of sound on a laptop, let’s consider several special cases:

• I can't hear anything through the laptop speakers, but there is sound through the headphones. The cause of this phenomenon is most often a physical malfunction of the speakers. Try connecting external speakers.
• Some users periodically lose sound (or experience extraneous noise). This problem usually occurs when the sound card is damaged or not working correctly. Try connecting an external sound card.
• If the sound disappears when playing certain audio and video formats, then it makes sense to update the list of codecs. Install the latest version of the K-Lite-Codec kit to eliminate this system flaw.

If you have tried everything and no longer know how to adjust the volume or where the sound went, then contact a service center - perhaps the problem is more serious than you initially thought.

Today we want to talk to you about one problem that our clients often come to us with. The problem itself is quite simple, but many people still cannot figure out on their own why the sound on the laptop disappeared, what to do in this case and how to fix the problem.

We will try to consider and remember all the possible reasons that we have encountered in our practice. If some of them seem ridiculous and funny to you, then don’t be surprised - this happens. Therefore, it will not be superfluous for you to check them too. And if nothing helps at all, then write in the comments or contact our laptop repair service.

We also draw your attention to the fact that if you are the owner of a computer and you are faced with a similar problem, then there is a special article for you “What to do if the sound on the computer is lost.” After all, computers are different from laptops and therefore there are some differences in solving this problem.

Speakers are muted or the volume is set to minimum

Do not rush to look for the nearest laptop repair service; the first thing you need to check if the sound on your laptop does not work is the current set volume. In the lower right corner of the screen (near the clock) there should be an icon that is responsible for it. Click on it and turn the volume to maximum.

Turn the volume to maximum

Also make sure your speakers are not muted. In this case, the icon will be crossed out with a red line.

Check if the speakers are turned on

Often laptop manufacturers stuff their devices with proprietary programs and utilities, which can also change the device settings. Find the keys on your keyboard that have a picture of a speaker. Usually these are three buttons at once: increase the volume, decrease the volume and turn off the speakers.

If there is no sound on a laptop with Windows 7 or XP, then try pressing these special keys. Usually you need to press it simultaneously with the “Fn” button, but it happens that without it. Make sure your speakers are turned on and the volume is set to normal.

There is sound from the speakers, but not from the headphones

If this is your situation, then there may be several options.

• Option one – the headphones themselves do not work. Try connecting them to another device and check. Or connect other headphones to this laptop.
• Option two is incorrect settings in the sound manager. Find “Sound Manager” in the lower right corner of the screen and dig into its settings. Perhaps you or someone else changed something there before, but now you don’t know what to do and why there is no sound on the laptop.
• Option three – the connector itself is faulty. Everything is clear here - you will have to contact a service center for laptop repair.

By this reason we mean a whole complex: the sound driver is not installed at all, the driver has crashed or there is an error in its operation, etc. If you open Device Manager, there should be no yellow icons or exclamation marks in the Sound, Game, and Video Devices section.

Despite the fact that there can be any reason why the sound does not work on the laptop, the solution will be the same. You need to reinstall the driver.

To do this, go to the official website of your laptop manufacturer and look for your device model in the “Support” (or “Service”) sections. After that, select the operating system that is installed. And we find the necessary driver to download. Once downloaded, install it.

It is difficult to imagine that this could happen by chance or on its own, but nevertheless we recommend checking this option. If there is no sound in Windows on a laptop, then in the same “Device Manager”, look to see if the device is turned on. If it is turned off, the icon will be the same as in the presented screenshot.

Right-click on such a device and click “Engage”.

Another reason that is unlikely to happen on its own. But we have encountered it in our practice, so we tell you what to do and how to fix it if the sound suddenly disappears on your laptop.

Go to BIOS and find the “High Definition Audio” item there. Make sure its value is set to "Enable", which means "on". If this is not the case, then install what you need, save the settings and restart the laptop.

Windows Audio service disabled

If you have Windows XP or 7 installed on your laptop and there is no sound, we recommend checking if everything is ok with the “windows Audio” service. To do this, open “Control Panel” - “Administration” - “Services” and find it in the list. Double click on it, properties should open. The startup type should be “Automatic”, and the service itself should be enabled.

Check the Windows Audio service

Internal speakers are faulty

The most unpleasant situation of all. And in this case, you will definitely have to take the laptop to a service center, unless you are a computer technician yourself.

Everything is checked quite simply: if there is silence from the speakers, but there is sound from the connected headphones, then the speakers are faulty. Although it is also possible that they simply forgot to connect them if they had previously disassembled the laptop.

We hope that our article helped you figure out what to do if the sound on your laptop disappears or does not work. Now you know how to fix this problem. If you have any questions, write in the comments or contact us to repair your laptop.

No sound on laptop - what to do

Every laptop user may encounter such a problem as no sound. This can happen at any time and on any device. However, you should not panic - most likely this is a minor problem that will not be a problem to fix.

Reasons for sound loss

The reasons for computer silence can be divided into two groups:

1. software;
2. mechanical.

The first group includes problems that are associated with errors and malfunctions of computer software. The range of such problems is very wide: from register errors to driver failure.

The main software reasons include:

1. the volume is set to minimum;
2. sound muted;
3. the service responsible for sound is turned off;
4. sound device drivers are damaged;
5. The required codecs are missing.

The last reason relates to the media player. In this case, there will be no sound in a certain program, or when playing some files. You should install another player or new codecs to an already installed media player.

Mechanical failures are considered more serious. In this case, laptop components fail, such as: sound card or module, speakers, connectors. It is unlikely that the user will be able to cope with such breakdowns on his own: most likely he will have to resort to the help of a specialist.

The following mechanical faults can be mentioned:

The last two fault options can be easily calculated; to do this, you need to connect and disconnect speakers or headphones. However, the reasons why the laptop does not sound may be more banal and simpler.

Volume muted

This is a very common situation that can make the user nervous. On the vast majority of laptops, the volume is turned off by pressing a combination of two keys, and on some - one.

The sound will be muted if you press the combination of “Fn” and the mute key. Usually it is located in the service key panel “F1-F12”. For example, for Acer laptops, the volume is turned off by simultaneously pressing “Fn” + “F8”.

Video: no sound on windows 7

The service responsible for sound is disabled

This is not an uncommon accidental error.

To check audio services:

You may also find the “Driver” tab useful, but more on that in the next paragraph.

You can access the configuration settings in another way, this requires:

Driver corruption

Drivers, like other software elements, also fail. More often this happens when the system has not been reinstalled or drivers updated for a long time. Usually reinstalling the driver will solve this problem.

You can access your laptop's audio driver management as follows:

In this menu, you can update the driver to a new version, or, on the contrary, roll it back to the previous version. This should be done if the sound has disappeared after reinstalling or updating the driver. Then the system will return the previous configuration of the sound controller.

Briefly it can be written like this:

You can also access the sound controller settings in the way described in the previous paragraph: through the sound settings icon on the bottom panel of windows.

If there is no “Update” command in the “Driver” tab menu or it is not active, you will have to install the driver manually. This should only be done from the official website of the company supplying the equipment. Often in the same window there will be a link to the manufacturer’s official website; if it is not there, you will have to search for the driver by the name of the equipment.

You can determine the type of hardware, device, or controller in Device Manager. This menu is located in the Control Panel, System and Security section. You can also call the dispatcher through a search in the Start window.

Sound card problems

If the malfunctions do not disappear after reinstalling the drivers, most likely the sound card has failed. Then in the properties of the controller there will be a message about malfunctions in the “status” item. You can try running the standard Windows troubleshooting service.

If this action does not resolve the problem, and the status line of the controller indicates that it is working with errors, you should contact the service center. Most laptops have a sound module integrated into the motherboard, which the average user cannot repair.

A way out of this situation may be to use an external sound card. Such a device is connected via a USB port and can be quite large. But the characteristics of the external card significantly exceed those of the built-in one. Considering the cost of the product, it is difficult to unambiguously assess the feasibility of such a solution.

Fixing sound with Microsoft Fixit Audio

Microsoft Fix it Audio is a small, simple program that can help you quickly debug sound on your computer. You can download this program from the official Microsoft website.

The program will check all the points that were described above, but in automatic mode. In addition, several additional features should be highlighted.

After verification, you will be notified if:

1. it starts the windows services that are responsible for sound;
2. sound devices are disabled;
3. volume set to low;
4. the installed device is not the default playback device;
5. the module is not connected;
6. problems with HDMI ports;

The application also has the ability to debug the webcam and Skype.

This program performs all possible debugging operations automatically. This will be done faster and better than if you perform the same procedures through the control panel menu or sound settings.

Microsoft Fix it Audio is a simple and reliable tool that will solve audio problems caused by software glitches. Search and debugging are done literally in one click, so even a user who is not familiar with electronics can use this service.

It will be quite simple to return the “voice” to the laptop if the failure is not mechanical in nature. How to do this: perform a step-by-step configuration check or use the Microsoft Fix it Audio application - it's up to you.

The first step is to check if the volume on the device is turned off and if there are any problems with the media player. If these steps do not bring results, it is advisable to use Microsoft Fix it Audio: the program will save your time, and the check will be performed thoroughly.

Hello, dear readers! Today, we will discuss a very popular problem - loss of sound on a computer or laptop. How to get him back and why he disappeared - this is what we will try to figure out. There can be a lot of problems with sound, and of course, the solution to them must correspond to the problem.

No sound on laptop, what should I do?

Introduction:

I decided to write about this topic because my friend recently called me and shouted: “I lost the sound on my laptop, what should I do?!” , after which I came to him, and we looked for a solution for quite a long time, but we still found it, let’s discuss it together 8)

Let's think about the reasons for such problems. But the reasons are mechanical and software, and their solutions are different.

The most common reason is the volume, or simply turning off the sound. A huge number of people simply forget about this and begin to panic prematurely. You just need to adjust the volume or check if the sound is on. On laptops these are the key combinations Fn+F* (* is the number of your F key, that is F1-F12), the combinations on each laptop are different, for example on my Acer Aspire 5553G it is Fn+F8, these buttons have speakers on them. And on desktop computers, check the volume control or speaker plug. By the way, here is an excellent program for sound: wink:

If for you everything is not so simple, then we continue:? In second place for sound problems is the driver of your sound device or chipset. Sometimes mystically, sometimes after installing this or that software, the sound card driver “flies” into oblivion:twisted:

But the solution is very simple, all you need is:

1. Find your sound card in the device manager (Computer -> right mouse button -> Properties -> Device Manager) and update its driver:

2. And then there will be options for automatically searching for drivers or manually, of course, try automatic first, but in 99% of cases it will not give anything (it seems to me that these “automatic functions” in Windows were made solely for beauty: lol:) and we will have to look for a suitable driver yourself.

3. In the same device manager, right-click (right mouse button) on our sound device -> Properties -> Information, and select the equipment ID:

4. Copy any of the lines that appear and go to the devid.info website and paste our “ID code” into the line where it says “Enter driver code” and click “Search”. After which we get a list in which we select our operating system (2000, xp, vista, 7, 8) and on the top driver from the list, click on the floppy disk and download the driver we need.

Notes: 1) If the list on devid.info is empty, then copy another line from the “equipment ID” section; 2) If your operating system is not in the list of drivers, then simply select the latest one, that is, if you have Windows 8, and the drivers on devid.info indicate drivers for windows 2000, windows 2003 and windows xp, then select windows xp and. etc.

5. We downloaded the driver, as a rule - it comes in the archive. Unpack it to any place convenient for you (the main thing is to remember where), and return to step No. 2. And we no longer select “Automatic search for drivers”, but manually, and indicate the place where the driver that we downloaded was unpacked.

Reboot the computer and listen to music, if it appears, then great! If not, then we continue on our way 8)

So, we still have no sound, but it doesn’t matter, we’ll figure it out now 8) These were software reasons, let’s look at the mechanical ones. If you are using a desktop computer with an on-board audio card (which is soldered into the motherboard), then all that remains is to check the speakers, connect them to the player, phone or tablet and play a music track, if there is sound, then the problem is in the sound card, and if it soldered into the motherboard, you can buy a new one and use a removable one: (If there is no sound on the player either, then it’s clear that the problem is in the speakers.

With laptops it's even more difficult. Laptops have built-in on-board speakers, and to replace them you will have to disassemble the laptop. But there are also advantages: you can plug a 3.5mm audio plug into the laptop and play the track. And then build on the results obtained. As a last resort, there are external sound cards that are inserted into USB ports and replace damaged ones.

No sound on laptop, what should I do?

No sound on your computer or laptop - what to do?

Every modern personal computer or laptop is equipped with a sound card that allows you to reproduce sound. Laptops are also equipped with built-in speakers, so they can sound without any additional devices. This article describes what to do if there is no sound on your PC or laptop.

Volume level

Before you start adjusting or repairing anything, check the volume level on the system and on the playback device (headphones or speakers). Many users often forget about this parameter and worry that something is broken. In fact, you (or someone else) may have accidentally turned the volume down to zero.

To restore the volume to normal level, you need to click on the speaker icon in the tray (to the left of the system clock). In the small window that opens, you need to change the volume level. Also notice the icon at the bottom of the window. If it is crossed out, it means the sound has been muted in Windows. Click on it to turn it back on.

Also open the Mixer section using the hyperlink below. Here you will see a separate slider for each of the running programs. The sound may be fine, it's just disabled for the app you're currently using.

Hardware mute

If there is no sound on your laptop, you may have accidentally turned it off using a special keyboard shortcut. Which models have this feature? Check the number keys as well as the "F1-F12" row.

If any of these buttons has an icon in the form of a crossed out speaker, you must press it. In this case, you should hold down the Fn service key, which is located in the bottom row, not far from “Alt” and “Control”.

If you are using external speakers, make sure they are also turned on. This seems obvious, but even experienced users can forget about such a small thing and spend a lot of time looking for problems.

Setting up playback devices

The next thing to check if there is no sound on your laptop or personal computer is the default playback device. Perhaps, instead of using speakers or headphones, Windows supplies sound to an unused HDMI output or virtual test devices. You will need to do the following:

Restarting the computer

Special services are responsible for playing and recording sound in the operating system. Sometimes, as a result of a system failure, they may freeze and begin to work incorrectly. In this case, you just need to restart the device. Rebooting Windows will restart all active services. If any of them were not performed, the problem will be resolved. This method should not be neglected. Despite all its primitiveness, it is capable of eliminating many problems.

Driver Update

A driver is a set of programs that “teach” the operating system to work with a specific device. In this case - with an installed sound card. As a result of viruses or crashes, the drivers may have been damaged, which caused the problem.

To restore sound, you need to do the following:

If the computer tells you that it could not find the update package, then you will have to search manually. Go to the website of the manufacturer of your laptop or motherboard (or sound card, if you are using a discrete one) and download the latest version of drivers from it.

Very often the installation package does not contain an exe file for installation. In this case, you need to click “Update drivers” again in the device manager and specify the location of the downloaded distribution. Don't forget to unpack it first using an archiver program.

Sometimes, due to certain life circumstances, it is necessary to install an operating system. Quite often, users discover that the sound has disappeared after reinstalling the system.

The possibility of a situation where the sound disappeared after installing Windows 7, unfortunately, is far from uncommon. Fortunately, it can be solved quite simply if you know exactly the reason.

Possible reasons

There may be several reasons for the sound to disappear. The main ones are hardware errors, that is, a malfunction of the sound card. In this case, you cannot do without specialized help. Or there are problems in the software, and specifically, in the lack of drivers for the sound card.

If the problem is with hardware, then you are unlikely to be able to solve the problem without special equipment and skills. Solving software problems is much simpler and does not require special knowledge and skills. To do this, you just need to confidently use the computer and not be afraid of it.

Solutions options

So, if after installing Windows 7 there is no sound, then the first thing you need to do is check the connection of the audio system to the computer, and also that the audio system you are using is selected in the settings. The check is as follows:

If the audio system is turned on and in use, but there is still no sound, then the most likely reason why the sound may disappear is that after reinstalling Windows 7, the drivers for the sound card or audio device were not installed. This problem is not so terrible and quite easily solved.

Finding and installing drivers

There are several ways to return sound after reinstalling Windows; the easiest way is to install control program distributions from the media that comes with the device; it contains all the necessary drivers. But if it happens that there is no disk, you can install the drivers using standard Windows tools.

So, to convince the OS to reinstall the drivers, follow the path indicated in the address bar of Explorer: “ Control Panel» → « system and safety" → "". And select " device Manager».

After completing these steps, the following window will appear:

In the window that appears, select “ Sound, video and gaming devices" and from the list that opens, select the desired system by double-clicking on the name. A properties window will appear in which you need to select the “ Driver».

In this window, you need to select the Update... button, and in the window that appears, click on the item “ Automatically search for updated drivers" After this, Windows will begin to search for the program on the Internet and update or install it if such a need exists.

Manual installation

If the built-in Windows service tells you something like “The installed software for this device does not need to be updated,” this does not mean that you actually have it installed and do not need to be updated.

If you just installed the system, then there are no audio drivers there. But the system simply failed. Also, quite often the automatic update service cannot find the necessary software, in this case the direct path is to manually search and install the necessary programs.

To do this, the first thing you need to do is decide which sound card you have installed. If your card is integrated into the motherboard, then most likely it is from Realtek, which means that you need to go to the manufacturer’s website and download the necessary software there. Device Manager identifies built-in cards as High Definition Audio Device.

But since you may have another audio card, it’s better to find out which one in advance. To do this we follow Start, we find " Execute" and write in the search bar " dxdiag" and click OK.

In the window that appears, go to the “ Sound" (sound).

Line " Name"(name) will tell you what card you have installed. After that, feel free to go to the manufacturer’s website and download the latest version of the software for your card.

After installing the software, restart the computer and check for sound.

Using driver packs

If you have already tried everything, but after reinstalling Windows 7 the sound still does not work, then you have two options. The first is to take the computer to a service center or use specialized software to install drivers, for example. It is better to download it from the official website.

After launch, the program will diagnose the system and indicate those drivers that need to be updated. It will also select the software recommended for installation. Among other things, it will contain Avast And Yandex browser, if you don’t need this happiness for nothing, find the button at the bottom of the window Switch to expert mode and manually configure what should be installed.

Feel free to install all the recommended drivers, but here are the software and programs that DRP suggests deleting, better viewing and changing the settings to those that suit you. The program may remove something you need.

Windows 7 Sound Service Problems

Sometimes the drivers are really fine, but problems arise because the audio service does not start. First, try changing the system sound a couple of times:

Hardware problems

If all the previous methods did not bring the desired result, then most likely there are problems with the hardware. An audio card may fail due to the failure of some individual elements, and not the entire board as a whole. But this will not reassure owners of integrated cards at all. The built-in cards are not repairable, so if it fails, you will have to buy a discrete sound card.

Discrete cards, as a rule, can be repaired, but you should not try to repair this device yourself without the appropriate skills and equipment; most likely, you will only aggravate the situation and spend much more money than if you gave the card to professionals.

Reasons for refusal:

• overheat;
• burnout;
• raw contacts;
• broken conductors;
• broken plugs;
• loose soldering;
• developer error or manufacturing defect.

To extend the life of your computer, clean it several times a year. This will allow the cooling system to perform its function most efficiently and problems such as overheating and damp contacts will most likely not affect you.

However, the lack of sound is not always a consequence of the fact that the audio card has failed. The first step is to check the functionality of the audio system; to do this, simply connect other speakers to the computer.

Also, cords can fail, replacing which is not difficult, this is especially true for headphones.

It is not always possible to determine at home without equipment whether the audio card has really failed or whether there is a problem with another device. Therefore, you should not panic right away; it is best to carry out diagnostics at a service center, and also update your computer software.

Video on the topic

Users often encounter this problem when the sound suddenly disappears on Windows 7. The reasons can be completely different. Depending on them, the methods of eliminating the problem themselves differ. It is important to understand that any information related to your computer will help solve it. Often faced with this problem:

1. Tried to update the drivers for the sound card or any others.
2. Connected other speakers to the device.
3. Reinstalled the Windows operating system.
4. Made changes to system settings and registry.
5. Installed additional software to improve your computer.

If your sound card worked fine before reinstalling Windows, but now it fails, then the problem most likely lies in the drivers. In this case, the volume icon can be displayed quite safely in the tray, and after reinstalling Windows will notify you that it has installed all the drivers. However, this does not mean that the drivers were installed correctly and are suitable for your sound card.

To fix this problem, you need to do the following:

1. If you have a laptop, then simply go to the manufacturer’s official website and download the latest drivers for your model (this is a whole update package, so you don’t have to look for a specific driver);
2. You can also look for a disk with all the drivers, which usually comes with the computer and other disks (for example, for installing Windows).
3. If you have a desktop computer, then you need to find out the model of the motherboard.
4. Then go to the official website of the motherboard manufacturer (that is, not your sound card or audio chip) and download the driver package from there.
5. After completing the steps and installing the drivers, do not forget to restart your computer.

Checking the correct connection and functionality of the speakers

To figure out why the sound on the computer disappeared, although it was there just yesterday, let’s look at a few main points. First, check if your speakers or headphones are turned on correctly. It is possible that one of your family members accidentally turned off the speakers or plugged the plug into the wrong socket.

In any case, double-check that the speakers and other equipment on your computer are connected correctly.

If you are sure that everything is connected correctly, try checking the speakers themselves. To do this, connect them to another device: player, phone or TV. If they work, then the problem is in the computer itself.

Windows Settings

The next thing to do is find the volume icon in the tray and right-click on it. A context menu will appear. In it you need to select the line “Playback devices”.

In the window that opens, check which device is used as an audio output (that is, playback devices, not recording devices). By default this should be your computer speakers. All the necessary information about the sound card on the computer will also be indicated here. If you are using an additional audio card (USB), it may currently be used as the default device, so change it to external speakers.

If the playback device is selected correctly, then select the speakers in the list and go to the “properties” tab. Here's a closer look at each individual tab:

1. general (information about the audio card will be indicated here, and by clicking “properties” and going to the “drivers” tab, you can check the presence and date of installed software) make sure that in the “use of device” section it is “use”;
2. levels (check that the volume sliders are not at the very minimum);
3. improvements (it is advisable to disable all effects);
4. SRS Audio Enhancement;
5. additionally (here click on the green triangle “check”, an audio signal should appear, check that the default format is “16 bit, 44100 Hz”).

If all the settings are set correctly, but there is still no sound on the computer, then we look further for the root of the problem. In addition, if you use special software to configure the audio system, then check all the settings there.

Playback devices are empty

If, when you go to the playback devices on your computer, you find that there are absolutely no devices there, then you need to do the following:

• Right-click on the empty space.
• A context menu will appear.
• Check two boxes: show disabled and disconnected devices.

After these steps, all your audio devices should appear in the window with the “disabled” mark. Therefore, we right-click on the speakers and select “turn on”.

We carry out similar actions with other devices, for example, headphones. If you managed to do everything correctly, then there should be no problems.

Playback devices are on but there is no sound

It also happens that a green checkmark is displayed next to the playback devices, notifying that the device is working, but there is still no sound. Connect other headphones or speakers to the computer again. Still no audio signal? So the problem is definitely not in the speakers. We continue to search further. The drivers for the audio card may not have been installed correctly. Therefore, it would be useful to remove them again and install them again. In order to do this, you need to go to the device manager. Therefore, open Start and enter “device manager”.

Or open the toolbar, go to the “Hardware and Sound” block, and then “Device Manager”.

The “Device Manager” itself will open. Here you need to remove all sound drivers installed on your computer. To do this, right-click on them and select “delete”.

After you remove all audio drivers, restart your computer. Immediately after turning on, it should automatically begin searching for missing drivers and installing them.

Usually, this procedure helps restore sound. You can also solve this problem by performing a system restore.

There are strange symbols in the device manager

The next problem is when the user installed Windows 7 on his computer and everything except audio works fine. If you start Device Manager, the following icons will appear next to the drivers.

This usually means that outdated drivers are installed (you have Windows 7, but the drivers were installed for XP). If you are unable to download other drivers, then to fix the problem, you need to do the following:

Turn on sound in BIOS

It also happens that a virus or any other malfunction simply disables the sound card in the BIOS settings. To make sure everything works, you need to do the following:

Checking the health of services

The next thing you can check is whether the Windows Audio service is running on your computer. To do this, you need:

• Open "Start" - "Control Panel".
• Select the “system and security” block.
• Open "administration" - "services".

For easier searching, sort services by name. Find the line "Windows Audio".

Make sure this service is enabled. To do this, look at the information in the “status” column - it should be “working”, as well as the startup type “automatically”. If one of these is indicated differently, then right-click on it and change the parameters we need.

After this, don't forget to restart your computer. If this doesn’t help, then we move on to desperate measures and try to use the problem-finding utility built into Windows.

Windows Diagnostics

Many users are quite critical of this function. However, she should not be underestimated. Especially in cases where nothing seems to be helping. To begin diagnostics, you must do the following:

An additional dialog box will open where you can select a specific area to troubleshoot. Since we are now trying to configure the sound, we select the appropriate “sound and equipment” block.

Then the “playback” item.

You will see a built-in service for troubleshooting Windows problems. For the utility to start working, you just have to click “next” and wait for its results.

If Windows manages to find the source of the problem, it will automatically download the missing drivers or return the default settings. All you have to do is restart your computer.

Audio card malfunction

If none of the above actions help, then most likely your audio card or other hardware has failed. You can try to perform a system restore or a complete reinstallation of Windows. Especially if you are sure that nothing could have happened to the computer, and the problem appeared after you installed a new operating system. Don't forget that the audio card is exactly the same part of the computer as RAM or processor. Therefore, it has a limited validity period. Perhaps the fact that you have lost sound indicates that it’s time to change it.

In contact with

As it usually happens - “I’m sitting, not touching anything, listening to music, and then BAM and the sound is gone.” Well, or when you turn on the computer, the sound does not play.

Or maybe it’s not there when you enter the toy? In this article we will look at the possible reasons for the loss of sound. This may seem banal and familiar to some, but not everyone knows this.

1) We check the sound in another music player, simultaneously increasing and decreasing the volume in it.

2) We check the speakers/headphones with the volume control.

3) Checking the connection. Perhaps the wire has simply come loose (which should be plugged into the Green socket or with a picture of headphones).

4) Right-click on the Dynamics icon on the Taskbar in the lower right corner and select Open Volume Mixer and check everything there.

5) You can click on Speakers right there, a window will open in which you can “walk” through the tabs.

The correct operation of the audio will be indicated by a corresponding inscription under its name and a green check mark next to the device icon.

In particular on the tab Additionally there is a Check.

On Windows XP:

Start - Settings - Control Panel - Sounds and Audio Devices.

On the Audio tab, in the audio playback section, make sure your device is correctly identified and set to default:

Go to the Volume tab. Make sure that there is no checkmark next to the “Mute sound” item.

It is also necessary that the mixer volume be set above zero.

6) We do the same as in step 4, but select Playback devices.

7) Increase the volume directly on the Taskbar by clicking LMB on Speaker.

8) RMB on My Computer - Properties - Device Manager - look at the line Sound, video and gaming devices.

On Windows XP:

RMB on My Computer - Properties - "Hardware" tab and click "Device Manager".

Of course, everything there should be as on the screenshot, no exclamation marks.

You can do this: RMB on the device, select Disable, and then Enable again.

If there are exclamation marks, it means you need to update the drivers. Either through the installation disk, or in the way that I described in the article which video card is installed.

9) You can check the BIOS to see if this feature is disabled.

Due to the fact that their versions are different, I can only use my own example: the “Devices Configuration” menu item and the “High Definition Audio” sub-item - the switch opposite it should be in the “Enabled” position.

10) Start - Control Panel - Administrative Tools - Services.

We find our Windows Audio service, if it is turned off, then turn it on. The startup type should be "Automatic".

If turned off, then RMB and Properties.

11) Check the sound by connecting other speakers or headphones.

12) If you have several audio outputs (Green connectors), for example like me, both on the front of the system unit and on the back and in the speakers, check everything.

13) The worst point and the worst reason is that the sound card burned out.

Don’t forget to reboot after completing “events”.
