After turning off the computer, the sound disappears. Standard Windows functionality

Youtube

Why is there no sound on Windows 7? Perhaps many Windows users 7 this problem has occurred at least once. This article contains the most common causes and ways to solve them.

The main reasons leading to loss of sound, as well as ways to solve them

Why does the sound disappear on a laptop, computer, etc.? In most cases, the reason for this is the user's own errors in handling the operating system.

So, what to do if the sound on your laptop does not work. The first step is to check the availability of the necessary drivers for your sound card. Perhaps they need updating, or you don't have them at all. By the way, driver errors are half the reasons why sound accompaniment on a laptop. In order to see which devices on your laptop or computer need driver updates, you need to open the device manager, which can be found in the control panel.

The manager window organizes and presents all drivers installed on a laptop, computer, etc. Using it, you can check the availability, functionality or relevance of drivers. If any item is marked with a yellow triangle, you should pay attention to it! Devices responsible for sound playback are located in the “Sound, gaming and video devices” tab.

Perhaps the most banal, but at the same time the most common reason for which the sound disappears is its unconscious turning off in the mixer. A mixer is a system with which you can adjust the volume specific applications. You can open the mixer by clicking on the corresponding inscription in the volume control window. After starting the mixer, make sure that all parameters are non-zero.

No less common is another reason why the sound on a laptop or desktop computer disappears. Its essence lies in the system disabling the output devices themselves. The reason for this may be system errors, device configuration changes and user intervention. To correct this problem very easy! For this:

Another common reason is that the service responsible for playing audio is disabled. To start it again, you need to go to Control Panel - Administration - Services. In the window that opens, find the “Windows Audio” service.

If the service is disabled, double-click on the service to open the settings window, from where you can force the service to start by clicking the “Run” button.

In this window, you should configure one more parameter – the startup type. This parameter is responsible for starting the service when booting Windows. In order not to constantly start the service manually, I advise you to define this parameter as automatic.

No sound from the front panel

What to do if there is no sound on the front panel or no sound at all? The whole problem lies in the question “Why is there no sound?”

In most cases, the front panel requires a Realtek controller to operate. If for some reason you don’t have it, be sure to reinstall it. After launching the manager from the control panel, go to the “Speakers” tab. Next, double-click on the folder icon on the left top corner, check the box next to “Disable front panel jack detection”

If, after completing the operation of displaying information on the front panel, the panel is still missing, it means that the BIOS installed in your laptop or computer is most likely incorrectly configured. The BIOS system is present in any laptop, computer or tablet, and provides the operating system with API access to the hardware, including the front panel. To configure the BIOS for the front panel to work, you need to:

When the system starts, namely during the demonstration of the manufacturer’s logo motherboard installed on your laptop or computer, press and hold the “F2” key to exit to the BIOS menu.
Then you need to find and select “Onboard Devices Configuration” in the “Advanced” tab.
In the next window, you need to configure one parameter, namely “Front Panel Type”, which is responsible for the type of front panel. There are usually 2 options: HD Audio and AC97.

Installing an audio device is not at all difficult. Just connect its outputs to your computer and you can get to work. But when there is no sound, then curses are followed by search queries. After all, there are dozens of reasons for the lack of sound that baffle even an experienced user.

Lack of sound is rarely due to equipment malfunction. In most situations it is missing due to a poorly configured system. To resolve this issue, make sure your audio settings are correct. First of all, check the status of the sound driver. To do this, in Windows 7, open:

Control Panel>Devices and Printers. From the list of equipment, select the one you need and click on it. Then open the Driver tab and click Update. Specify the path to the CD.
Right-click on “My Computer”, then “Device Manager”. In the list that appears, find required device. Then click on it right click mouse and “Update drivers...”.

If the device is not in the list, then you need to install the driver for the sound card. DriverGenius is suitable for downloading the necessary components. A hacked version of the program can be found on the Internet. Besides updating, it will show information about your hardware. Knowing the sound card model, you can download drivers manually - using a search. More detailed installation tips are described in our.

Check your Windows service settings. To do this, press “Win + R” and enter “services.msc” in the dialog box. Find the “” service in the list and activate it. The startup type must be set to "Auto". Typically this service is turned off after reinstalling the operating system.

Let's look at driver configuration options. Go to Control Panel > Sound. Then go to the equipment properties - to the “Levels” tab. Set the volume level and enable audio. Check if the sound is muted by clicking on Realtek HD Manager in the lower right corner of the monitor.

Next, using the method of elimination, check the serviceability of the equipment. First of all, make sure that the device is connected to the correct connectors. For the microphone this is a red output, and for speakers it is green. See how the device reacts. When it is connected, the computer reports that the connector has been connected.

If you are connecting it to the front of the system unit and not directly to the motherboard, make sure that the cable inside the computer is not disconnected. The problem may arise if the motherboard does not match the type of audio output. Try changing the BIOS settings from “AC ’97” to “HD Audio” and vice versa. To do this, go to the “Advanced” tab and find “Front Panel Type” there. You can check the hardware on another computer. This will help you understand the reason for the lack of sound.

As a result of the system update, BIOS settings may be disabled. The parameter “ High Definition Audio", it should be "Enabled".

The sound card may be faulty. Using your sense of smell, check for any burning plastic odor. Also plug in your work headphones. If the sound still does not appear, then most likely you will have to replace the old part. But don't do this without trying every possible option.

If none of the options solved your problem, then we recommend calling a specialist to your home. If you wish, describe your situation on one of computer forums. Such searches will take more time, but there is a chance that a similar problem has already been solved before you.

Today we will figure out why the audio output device is not installed in Windows 10, although the drivers for the sound card are installed, and the speakers or audio system have not been turned off recently.

Physical damage to the audio playback device.
Often the error occurs due to the lack of software to control the operation of the sound card or the use of a fairly outdated one or one designed for previous ones. Windows editions driver version.
Incorrect speaker configuration.

Let's look at what to do in each case to solve the problem and return the computer to its normal operating mode.

Checking the sound system

Let's start correcting the situation from the first cause of the error. All that needs to be done here is to check whether the speakers, headphones or acoustics are connected correctly and make sure that the audio playback device is working properly by connecting it to another PC or smartphone.

Installing drivers

1. Find the manufacturer of the sound card (in the Task Manager, if the driver only needs to be updated, or in the instruction manual for the PC or motherboard/sound card).

2. Go to official resource device support.

You should only install the driver downloaded from the official website! Using the Update Center or driver packs in such situations is often the source of the problem.

3. Download from there the version of the sound driver installer intended for Windows 10 of the appropriate bit depth (you can find out through the “System” item in the Win→X menu).

4. Launch the installer and install the driver.

5. After completing the operation, be sure to restart the computer.

If installing the updated software did not help, move on.

1. Open “Device Manager” using Win→X.

2. Find the sound device in sound, gaming and other devices.

3. Open its “Properties”.

4. Click “Roll back driver” and confirm the operation.

5. Upon completion, reboot.

We correctly indicate the device for playback

The last option to solve the problem is to select the necessary equipment for sound playback. Perhaps the wrong stereo system is used by default in Windows 10 (this is important when several playback devices are connected or there are virtual sound devices).

1. Open the context menu of the “Speakers” icon in the tray.

2. Click on the second item in the drop-down menu.

3. Select the current speakers.

4. Call up the context menu of their icons and click “Use as default” to make the speakers a device for playing sound.

You can also use the troubleshooting wizard (called through the speaker context menu).

After reinstalling the operating system, problems with sound reproduction often occur. Sometimes this happens even when the sound drivers, as the user thinks, are in place. How to fix the situation? What to do if the sound does not work on Windows.
There may be several reasons for the sound not working after reinstalling Windows.

Why doesn't sound work on Windows 7 and other versions of the system?

The root of this problem is sound. Inappropriate devices may be installed by mistake.

Reference. A driver is a utility program that is responsible for the interaction of a PC with various devices and third party equipment. If your operating system is missing a specific driver, visit the center web page Windows compatibility. Here you will find information about hundreds of devices and links to download programs. Drivers can also be found on the disc included with your device.

Sometimes the solution to a problem is much simpler than we might imagine. If sound does not work on Windows 10, do not ignore these simple steps.

Check that your speakers or headphones are connected correctly. Perhaps the cause of the sound problems lies in the cat’s self-will. It is worth making sure that the speakers are in good working order. To do this, connect them as headphones to your mobile phone.
See if everything is ok with the playback devices. This can be done by opening the section of the same name, which is located in the control panel. To get into it, click on the volume icon. Then carefully study the properties of the speakers.

If the computer is equipped with a special program that serves sound card, open it and check if the sound is muted. Obstacles to normal sound reproduction can be created by the optical output, while your speakers may be working.

In Windows Device Manager you can see if you have any sound cards.

By pressing Win+R, enter devmgmt.msc into the line that appears. Then go to the "Sound, Game and Video Devices" section. After clicking on the name of the sound card, open “Properties”. Here you need to look at the information about the “Device Status”.

Disabling sound in BIOS

In some cases, audio can be disabled in the BIOS. Therefore, take the time to check the settings of this set of firmware. To enter it, after turning on the PC, press “Del”, “F2” or “Esc”. Then the message “Press Del (?) to enter Setup” should appear. Instead of “Del” the required key will be indicated.

Next, in the menu that appears, select the “Devices Configuration” paragraph. The “High Definition Audio” item should be located here. If everything is fine, the value will be “Enabled”. It is not always necessary to reinstall the sound driver on Windows 7.

What should I do if there is no sound after installing Windows 7?

The fight against the problem should start from the control panel, or rather from the device manager. So, you will see whether audio devices are missing or installed. Most often it turns out that the necessary driver for sound is missing or the sound device is not installed.

Before searching the Internet for drivers, arm yourself with knowledge. First, find out the manufacturer and model of the motherboard. A receipt indicating the purchase of the computer or the markings on the motherboard will help you determine the model. Information about this element may appear when the PC is turned on.

If you own necessary information, then go to the manufacturer's website. Such resources have a section designed for downloading drivers. At the same time, do not confuse a resource belonging to the manufacturer of the motherboard with a website sound chip(famous Realtek). It’s even better if you still have the installation disk with drivers.

Now let’s talk in more detail about how to install an audio driver on Windows 7. You will have to follow the following steps to go to the “Device Manager”.

Right-click on the “My Computer” icon and go to “Properties”.
Go to the “Hardware” section by selecting “Device Manager”.
Select the line with, video and other devices" ( sound driver will be the first).
Taking advantage context menu, click "Update Driver".
Click on the option “Search for drivers on this computer.”
Specify the location where the driver is located, after which the system will begin updating.

Updating the driver may help get the sound back

You can install a sound device on Windows XP in the same way. If the official website does not have the required driver, you will have to spend more time. Help will be provided by specialized forums where users share ways to solve emerging problems.

A quick way to restore sound on Windows

If the sound does not work on Windows XP and some more later versions of this operating system, the problem will be fixed by the driver pack from the drp.su web resource. The Driver Pack Solution utility can automatically detect your sound card and then install the appropriate drivers. It is a set of different software devices with automatic installation system. With its help, you can install sound devices on Windows 8 in a matter of minutes.

Driver Pack Solution – effective tool for solutions various problems in the operation of a desktop computer, which cannot be said about overcoming.

The described methods for controlling sound in Windows 7 cannot be called a panacea. The problem could be much more serious. In addition, the methods listed above involve reinstalling the operating system. Therefore, it would not be superfluous to conduct a superficial check of the serviceability of sound devices.

Sound does not work on Windows 10: video solution

WATCH THE VIDEO

Now you know what to do if the sound does not work on Windows. Ask questions to the experts.

Sometimes, for no apparent reason, the sound devices on your computer stop working. The causes of the malfunction can be different: from complete shutdown, to hardware problems and sound failures of specific applications.

Hardware faults

If, when logging in, the message “No sound devices are installed” appears and a speaker icon with a cross appears on the taskbar, then there may be the following reasons:

The drivers did not have time to load and in this case a simple reboot will help.
The sound adapter is disabled in Windows Device Manager. This problem is also easily solved, just turn it on.
The driver for the motherboard chipset is not installed. The solution is to put it in.
Audio drivers do not work or are not installed. To fix it, you need to reinstall the drivers.
The audio adapter or sound card is faulty.

If you are not a specialist, then it is better not to try to fix this problem yourself, but to contact specialists.

After reinstalling the system

Sound functionality may stop working as a result of reinstalling the Windows operating system. In general, everything necessary drivers can be found on the manufacturer's website. But, for example, if the hardware is old and its support has been discontinued, searching for drivers may take great amount time.

To select the necessary software, go to Device Manager (Start-Control Panel-Devices and Printers) and look for the item “Sound, video and gaming devices”.

Although the device displays normally, no sound will appear unless the driver is installed. To find the right one, you need to find out which sound card is on your computer. To do this, you can use two ways: either look at search engine by ID, or use the AIDA program or its equivalent.

The most convenient way is to use the program. Download it, install and open it. Next in the window, select “Computer”, and then “Summary Information”. Everything that is installed on your computer will appear on the screen, including the connected sound adapter.

Having found out the name and model, go to the official Realtek website and its top menu click Download. Among the presented drivers, select High Definition Audio Codecs (Software). This version is the most universal, supports all new audio formats and is suitable for all versions of Windows. After downloading, run the file and follow the instructions and after installation, restart the computer, after which the sound will appear.

Which is devoid of multimedia merits, will turn out to be an almost impossible test of imagination. Because the first thing that comes to mind is the pointlessness of using such a technique. At the same time, many of the owners of a modern computing device do not notice how enormous and unimaginably rich the creative potential inherent in this machine is. However, the often occurring problem “sound devices are not installed” still makes the user think that without audio support, a PC is a very boring device.

Let’s not remain silent about the problem: for novice users, an unexpected “boycott” of the system often becomes a kind of test, from which not every newbie manages to emerge victorious. But you, dear reader, are in luck! In just a few minutes you will be able to correct the situation. Simple, but effective methods Restoring sound on a computer will help you detect and neutralize the unfavorable cause of electronic “silence” that has appeared out of nowhere. With your permission, let's move on to studying the material.

Audio controller - a device in which sound is generated

As you understand from all of the above, the article is dedicated specifically to those users who do not know where exactly to start when the system ambiguously reports that sound devices are not installed. Therefore, let's study the subject of our discussion in more detail.

Depending on the modification of the computer, the audio subsystem implemented in it may be of a discrete or integrated type. The most common is last view the device in question, the functionality of which is ensured through the coordinated operation of two basic elements: the controller host, which is part of the chipset " south bridge”, and a small chip located separately on the motherboard known as an audio codec.

However, in both cases, the process of troubleshooting the “sound devices not installed” type is almost identical, except for some nuances, which you will also become aware of from the material in this article.

Why the computer is silent: the main reasons and methods for detecting them

As practice shows, in most cases, problems with sound occur through the fault of the user himself. The main factor is the same inattention, as well as the reluctance inherent in many people to familiarize themselves with technical documentation PC. Often the user forgets to turn on the speakers or uses the audio jacks incorrectly. It's hard not to notice the crossed out speaker icon in the system tray, yet many people bother to ignore it. Probability mechanical damage one of the connecting cords is often also discounted during the search process sound faults. As a result of such banal omissions and an incorrectly assessed situation, the user begins to reinstall audio drivers, edit the registry, and, in general, experiment. As a rule, such rash actions lead to the previously mentioned problem. Therefore, to resolve the question: “Why are they not installed?” - you need to approach, so to speak, comprehensively and systematically, so as not to waste precious time and energy fighting “windmills.” However, let's move on.

What to do if we navigate the system on a computer

There are two types of malfunction: hardware and software. However, most often the “culprit” of silence is the second one. Therefore, to make sure otherwise, the first thing you need to do is check system settings sound device:

Click the Start button and go to the Control Panel menu.
Next, go to the “Device Manager” section.
Pay attention to the item “Sound, video and...”. If you see any “attention attributes” in it, then most likely the problems are caused by a malfunction of the installed driver.
When the user does not observe any deviations in the mentioned section, it is likely that the “silent error” is hidden in one of the system settings items.

Forced retreat

Of course, the service message: “Sound devices are not installed” requires direct user intervention. Basically, the absence or inoperability of a critical driver is resolved by installing current version corresponding software. However, we will not remain silent about the fact that when following the mentioned instructions, some complications may arise that will become a kind of obstacle to achieving the expected result. A little later we will definitely consider such a multifaceted issue regarding correct operation enabled audio driver. Let's return to the previous discussion.

Checking the enabled parameters of the Windows Audio service

As a result of using third-party software, as well as in cases where the OS is “infected” with malicious machine code, system audio settings can be changed. As a result, it is unlikely that you will be able to successfully install a sound device: Windows 7 will still be “mute” (however, like any other version of the Microsoft system) if the operating parameters of the OS multimedia service are deactivated.

Take advantage hot combination Win+R keys.
In the Run box, enter the services.msc command.
After the “Services” panel opens, you need to select “Audio Endpoint Builders” from the list presented.
After you double click mouse you will be taken to the service window of the service, pay attention to the “Startup type” checkbox: the value “Automatic” should be displayed there.
After changes made activate the “Run” button.

If the above steps do not work positive result, then proceed to the following instructions.

BIOS solution

Sometimes, in order to install a sound device on your computer, you need to use some parameters in basic system input/output. Depending on the manufacturer, as well as the version of the BIOS firmware, the sections in which the audio component is configured may vary (both in name and location in the BSVV environment). Therefore, it is necessary to study the computer’s operational passport in more detail. However, you can always focus on the generally applicable words Audio, Sound or Controller. However, only if you are absolutely sure that you are in a specific section, specify the Enabled or Auto parameter.

How to install a sound device

Windows 7 or the subsequent eighth version of the OS, when installing any driver, checks whether the current user has administrator rights. As you understand, the subsequent process of driver implementation is only possible if you follow the above instructions. Let's move on to the practical part of our material.

First of all, the old, broken audio driver needs to be removed. Moreover, with the subsequent use of a special utility (for example, CCleaner), the functionality of which has the ability to correct registry errors and uninstall residual entries in the Windows system log.
Only after a reboot will you be able to correctly install the sound device on your computer using stable version multimedia driver.

Learn more about the virus threat and an effective method for restoring the registry

As is known, harmful software can completely disable the operating system. In our case, it may well happen that an unattended virus can damage some system files, which, one way or another, will affect the full functionality of the OS.

Scan your computer for malicious code. It is worth noting that sometimes a traditional antivirus program is powerless in such situations. Therefore after standard process scan, resort to third-party “disinfecting” utilities, such as Malwarebytes Anti-Malware.

Attention: quite often a common problem for many, when the computer writes: “Sound devices are not installed,” is a destructive result of something that has become embedded in the OS malicious code. Subsequent user actions aimed at reinstalling damaged software are blocked by a virus program. Therefore, the above recommendation should not be neglected.

If software inconsistencies are detected, you must restart the PC. If the utility was unable to fix some problem areas of the OS, then you should resort to the process of restoring them. Select the previously created checkpoint and activate a system emergency rollback.

Other audio troubles, or What else prevents the user from installing an audio device

Working on a laptop is not only comfortable. Often a portable device is used as multimedia center, especially when the laptop owner considers himself an incorrigible music lover. At the same time, intensive use in a mode when the speakers are operating at full power will sooner or later lead to the natural inevitability - “they have served their purpose.” Therefore, sometimes the problem of lost sound is resolved purely technically - by replacing the stereo pair. This, in general, is an expensive pleasure. Seeing a certain generality in portable configurations, it is worth noting that most modern laptops (including desktop modifications) are equipped with an Audio HD-standard sound circuit, which implies the use of a special audio controller.

Why can't I record?

"Sound devices are not installed" on in this case is not a problem. The solution lies in the correct connection of the recording device and in the system settings!

Check that the microphone is inserted into the correct jack.
Open the Start menu.
Go to "Control Panel".
Enter the "Sound" section.
Now click on the “Record” tab.
If there is a microphone in the list of active devices, pay attention to the indicator located next to it. When playing sounds, you should visually observe how the graphic equalizer comes to life.
Otherwise, you need to make sure that the device is technically sound.
If the microphone is not in the above list, then right-click once in the work area of the service window. From context list select "Show unconnected...".
Then click the manipulator key on the found element and activate the “Use as default” item.

Summing up

Of course, much did not fit into the scope of this article, but you, dear reader, still managed to get acquainted with the main reasons for often occurring situations when sound devices are not installed and the microphone does not work. Nevertheless, let's hope that the above recommendations will help you overcome the “sound” difficulty as a winner. Remember: when none of software methods restoring audio performance does not help, this is a hardware malfunction. Therefore, be prudent and seek help from specialists. Congratulations to you and quality recordings!

Any breakdown or malfunction of the computer is unpleasant for the user. Especially often on forums people complain about a common problem - the sound on the computer has disappeared. It is impossible to completely determine the cause of this ailment without directly examining the car. But we can talk about typical faults related to problems with sound reproduction so that you can independently inspect your computer.

The good news is that in 90 percent of cases, computer sound problems can be resolved on your own without contacting specialized repair shops. To do this, simply follow our recommendations and advice, which we will describe in detail below.

Why is there no sound on my computer?

There may be no sound on your computer for several reasons, which can be divided into two groups: hardware and software. In the first case, the absence of sound is due to physical breakdown sound card, problems connecting the sound card to the motherboard, malfunctions in the motherboard. In the second case, the problem is related to incorrect sound settings, crashed drivers, or disabling operating system sound services.

At home, we will not be able to repair a burnt-out sound card, but we can check the quality of connections between system components and the correctness of the settings without any problems. This is exactly what we will talk about next.

Incorrect sound settings

Problem. Sound settings, or rather volume level sound effects V various applications They can always play a cruel joke on the user who thinks that the sound on the computer has disappeared because it is broken. At first glance, the situation seems trivial, but believe me, the volume level in the settings set to minimum is very often mistaken for a sudden breakdown. Both the user himself (by accident or carelessness) and the system (unforeseen failure) can do something wrong in the settings.

Solution. The solution to the settings problem is very simple and consists of checking the volume level in the volume mixer. You can get there by right-clicking on the volume icon, which is located in the lower right corner of the screen.

In the volume mixer we check the overall volume level and the volume level in different applications. Also, don’t forget to check if the sound is muted using the special buttons.

If everything is in order with the settings, but the sound on the computer disappeared and did not appear, then read the article further.

Problem. If there are any problems connecting the sound card to the motherboard, there will be no sound on the computer. This type of malfunction occurs less frequently than incorrect setting volume, but still occurs. You can check whether the sound card is connected to the computer in Device Manager. If nothing is displayed in the sound devices, it means that the sound card is most likely faulty, or there are problems with the quality of its connection.

Solution. Solving this problem requires certain minimal skills in handling tools, since you will have to remove the side cover of the system unit. This must be done by first turning off and de-energizing the computer.

After removing the cover, the procedure is as follows:

Remove the audio card from the slot
Look at the condition of the contacts; if they are dirty or oxidized, clean them
Check the condition of the connector; if it is dirty, carefully clean it with a brush
In case of general dust contamination of the system unit case, it is better to clean the entire case
Firmly insert the sound card back into the connector
Turn on the computer, check the functionality of the audio card and the presence of sound

A loose connection of the sound card can be the real cause of the problem: the sound on the computer is lost, so before contacting a repair center, be sure to check the quality of its connection.

Problem. Usually Personal Computer represents system unit, monitor, and connected peripheral devices (keyboard, mouse, speakers). The system unit does not have its own speakers, nor does the monitor (some models have speakers installed, but most often they do not). This means that if there is no connection between the speakers and the sound card, the user will notice that there is no sound on the computer. The first thing that comes to mind is thoughts of a breakdown or serious malfunction, but in reality the fault will lie with the speakers, which are not connected to the audio card.

Solution. If there is no sound on the computer, check the quality of the connection of the speakers or headphones to the sound card. It is quite possible that the cable from your sound system was pulled out of the audio card connector completely by accident.

Also, do not exclude the possibility of damage to the connecting cable between the sound card and the speakers. If such a cable is damaged, you will not hear any sounds when playing music files on your computer. If possible, check the functionality of the connecting cable.

Wrong playback device selected

Problem. If the playback device is set incorrectly in the sound settings, you will not hear sound on the computer. Let's explain with an example to make it clearer. For example, your sound card has two output connectors: a 3.5 mm line output (Rear L/R) and a digital optical output. You connect the most regular speakers 2.0 format to the line output, and playback devices are set to S/PDIF, which implies the use of an optical cable and the corresponding connector on the sound card. In this situation, you will clearly notice that the sound on the computer has disappeared.

Solution. To solve this problem, you need to specify the playback device in the computer settings that corresponds to the actual connected equipment. To do this, right-click on the volume icon and select “Playback devices”.

The sound disappeared due to a driver failure

Problem. If you checked the volume mixer and everything is fine there, but there is still no sound, then the problem may be with the drivers. When the sound card driver stops working or starts working incorrectly, the sound on the laptop disappears. People say about this problem “the drivers have fallen off” or “the drivers have fallen down”.

There may be several reasons why a driver may start to work incorrectly:

Viral activity
Conflict between installed programs
Software glitch
Sound card driver update fails

However, we are more interested not in the causes, but in the consequences and ways to eliminate the malfunction.

Solution. Before solving problems with drivers, you need to make sure that they are the cause. To do this, go to “Start” --> “Control Panel” --> “Device Manager” and open the “Sound Devices” tab.

If there is a yellow exclamation mark on the sound device icon, then the drivers for that device are damaged. The problem with drivers can be solved by reinstalling them. At software glitch or driver corruption as a result viral activity The driver needs to be reinstalled. When incorrect update It is enough to roll back the driver. We will look at these two procedures.

1.

To update the driver, select the sound card in the device manager, right-click and click on “Properties”.

In the window that appears, go to the “Driver” tab and click the “Update” button.

Next, we will be asked to choose how to search for the driver: on the Internet or from a specified location. If you have a disk or folder with drivers for your computer, then select the second method and indicate the location of the driver. If you don’t have drivers, choose the first method.

By the way, about updating drivers. We have already reviewed an interesting article on the topic of how to update a driver using the program DriverPack Solution. With its help you can very quickly find missing drivers not only to the sound card, but also to other devices.

2.

As we said earlier, a rollback is performed if the driver corruption is due to a failed update. To rollback, click the “Rollback” button and in the warning that appears, click “Yes”.

If you have lost sound on your laptop and this is due to the sound card driver, then the tips described in this paragraph should solve the problem. If the problem is not in the driver, then read on.

Problem. One of possible reasons no sound on the laptop - disabling the sound card in the BIOS. This disconnection may be due to a software glitch. It is also possible that the card may be disabled by the user due to inexperience. In any case, a disabled sound card can become a real source of the problem - the sound on the laptop disappears.

Solution. The solution to this problem is quite simple. You need to go into the BIOS and enable the sound card. After this, sound should appear on the laptop. You can get into the BIOS using special hotkeys. On various laptops these keys may be different. We recommend that you read the article “How to enter BIOS on any computer.” In this article we have provided hotkeys for large quantity laptops, and you can easily find your device.

After you have entered the BIOS, you need to go to the section responsible for the operation of built-in devices. Depending on the laptop model and BIOS version, it may be called differently (for example, Advanced Features, Chipset or Intergrated Peripherals). Next, go to the “Onboard devices” section.
