How to restore sound in a Windows 7 laptop. There is no sound on the laptop - what to do? How to find the right driver by motherboard model

Youtube

No sound on laptop, computer, computer- we shout. Of course, this problem is serious, because watching a movie, playing a game, listening to music without sound is like eating without food. It occurs quite often and there may be several reasons for this; we will consider them below:

1. There is no sound because the speakers are connected to the wrong jack

(if you have a desktop computer). To do this, you need to connect the speakers to the correct connector, green, and turn on the speakers accordingly.

2. There is no sound, because it is simply turned off (no matter how trite it sounds)

You just need to turn it on. There is (should be a column or speaker icon) in the lower right corner. If it is not there, most likely the drivers are not installed, go straight to step 5. Click on it and raise the slider to the end.

3. The slider is raised, the sound is on, but there is still no sound.

Most likely, especially if you have a laptop, another audio playback device is simply turned on. To do this, click on the icon in the lower right corner, then on “mixer”

We look at what device we have by default, there should be speakers (and your device). If not, then click right click Click on the icon in the lower right corner and select “playback devices”

Right-click on the device we need (usually speakers) and select use the default communication device. We save, close all applications (players, etc.) We try, it should appear.

4. There is no sound because your playback device is turned off in the system.

To enter the settings, right-click on the “my computer” icon and select “properties”, then “device manager”.

In the “sound, video and gaming devices» displays all your audio devices that are responsible for sound. If they have a cross on them, it means they are turned off. You need to right click on device/properties/enable. As you can see in the image above I have two devices: one standard Realtek High Definition Audio, second AMD High Definition Audio Device - additional - digital,
which transmits its signal through hdmi cable. Such sound playback devices are most often found on laptops with discrete video cards, and on all computers that have HDMI output.
Very often there is no sound after connecting a laptop from HDMI to a regular 3.5 jack (the plug on all computer speakers) and vice versa. You need to delve into the above settings and you will see a miracle - the sound will work.

5. There is no sound because the drivers for the sound card on the laptop or computer are not installed.

Solution: if you have a laptop, no matter what brand (Asus, Toshiba, HP, LENOVO, DELL, SAMSUNG, etc.), write to Google, Yandex request“download drivers for” the manufacturer of your laptop, computer, computer”, once on the manufacturer’s page, go to the downloads and support section, select your model and operating system and download the drivers for your sound card. Or read the article -

A somewhat complex sound subsystem is responsible for outputting sound from a computer to speakers or headphones. It is logical that there will be no sound if there is a problem at any stage along the sound path.

There are a great many sources of this problem: starting from a failure in Windows settings and ending with device malfunctions sound path. But before we talk about the reasons and how to fix it, let’s figure out what the computer sound system consists of.

Hardware and software

Audio card, A sound card or sound adapter is a device designed for processing audio data on a PC. Cards can be discrete (separate) or integrated, i.e. soldered to motherboard computer. The latter are the most common and are represented by two basic elements: an audio codec - a small microcircuit, and a host controller as part of the chipset (south bridge).

Operating system:

A driver that controls the operation of a sound card. If there is no driver, there will be no sound on the computer either.
Helper Utilities: Windows Sound and Audio Device Managers from Hardware Developers
System Services: Windows Audio Endpoint Builder
Codecs - set dynamic libraries required for playback sound files certain formats. Some audio codecs are present in Windows natively, others are installed as needed. The absence of some codecs is manifested by the fact that individual music files will not be played on the computer, but in general the sound does not disappear. Example codecs: mp3, wma, aac, etc.

To make it easier to understand why the computer suddenly became “deaf and dumb”, let’s divide the reasons into 2 groups according to the time of occurrence:

there has been no sound since the purchase or installation of the system;
There was a sound, and then suddenly it disappeared.

If there was never a sound

In this case, the problems relate to the hardware component and driver installation.

Connecting the speakers correctly

First, make sure that the audio card is installed correctly and turned on. Look at the back end system unit- jacks for microphone, speakers and headphones are located on the motherboard or slightly below - if the sound card is connected as an expansion card. There are at least 2-3 such sockets (microphone input, line input and linear output), at most - more than a dozen (on professional cards). On laptops there can be only one jack 3.5 socket.

In addition to the audio card, speakers or headphones can be the culprit for the lack of sound, so it is better to make sure that they are in order from the very beginning - check them on your phone, for example.

Check the speakers in each of the jacks, as the jacks may be reassigned in the Audio Device Manager settings, i.e. The sound output may not be on the green socket, but on the pink socket, for example. Let's see how their reassignment is done using the example of a utility from Realtek:

It should be noted that the ability to reassign sockets through the sound manager is not available everywhere. On those computers where it is not present, this is done by editing the registry.

Installing the sound driver

Look in Device Manager and check if you have installed sound driver. Without a driver, the sound card will be recognized as an unknown device. "Device Manager" and make sure it is there.

If you see a similar picture in yourself, and in the list sound devices There is no audio card - this is your case. It can be found on the disk from the motherboard, and if there is no disk, download it from the website of the sound adapter manufacturer, when its model is known. If the driver is installed, you will see a similar picture:

The main audio device you have 90% of the time is the built-in Realtek High Definition Audio controller. The rest of the devices (AWEI, DL-Link and XMOS) are my external gadgets. If Realtek is displayed without question marks or exclamation marks, then the driver is available. If, however, there is also “ Unknown device", then this is some other device.

How to find the right driver by motherboard model

It is best to use the program. If you act manually, then first you need to determine the “mother” model. One of the utilities for recognizing PC hardware will help with this, for example, free HWiNFO32\64 or CPU-Z. In HWiNFO necessary information displayed in the “System Summary” window, in the “Motherboard” field.

In CPU-Z – on the “Mainboard” tab in the “Model” field

Having specified the data, we go to the manufacturer’s web resource, in my example it is Samsung. Using the search, we will find a section on the site dedicated to the device. Open the “Support” -> “Download” tab/page, go to the “Drivers” subsection, select your OS version from the list and download the sound card driver (Audio, Sound Card).

Now all that remains is to run the downloaded file and press the “Next” button during installation. When finished, you need to restart the computer. We are also looking for a driver for a laptop based on its model from the label. If the reason was in the drivers, then the sound should appear.

Incorrect sound driver loading

Sound dropouts sometimes occur after incorrect installation programs and Windows updates. The problem is solved by removing the audio card in Device Manager and then rebooting.

After selecting the “Delete” item, the system will offer to remove the drivers for this device “to the heap”; there is no need to mark it.

After restarting the PC, the sound card will appear in its place again. If it doesn’t help, then repeat the process with “uninstalling the driver program.” Also find and remove the driver installation from standard tool"Add or Remove Programs" in Windows. Reboot and then install the drivers from scratch.

If you updated the driver and after that a problem appeared, then I recommend returning to the previous working version. To do this, in the device properties on the “Driver” tab, you need to click “Roll Back” and reboot.

Setting up the BIOS

Next you need to make sure that the card is not disabled. A sound-related parameter may be called: “Audio Controller”, “Azalia Audio”, “HDA Controller”, “OnChip Sound”, etc. with the words sound, audio, azalia, HDA. IN different versions BIOS it is located in the “Advanced” or “Integrated Peripherals” tabs. To enable an audio device, you need to set it to Auto or Enabled.

Is the computer still “deaf and dumb”? It is possible that the sound card is simply faulty. There are many inexpensive discrete audio cards on sale with USB interfaces, PCI and PCI-E, which can replace the built-in one in case of failure.

There was sound before, but it disappeared

The reasons are related to incorrect actions of the user or installed programs. Also, after infection with viruses, there may be various problems, including lack of sound. The problem is created by the activity itself malware and the changes it makes to the system (modification of system files and the registry by viruses and Trojans is a common occurrence).

First, of course, you need. For this, the capabilities of an antivirus that works “normally” in the system are often sufficient. But if after treatment the sound does not appear, you will have to restore Windows.

Checking audio settings in Windows

Look at the Speaker icon in the taskbar notification area. It may be that the volume level is at zero or even turned off, i.e. crossed out. To fix this, click on the speaker and move the slider up. This sounds stupid, but nevertheless, this happens due to carelessness.

If the speaker is marked with a white cross in a red circle, you need to check whether the playback devices are disabled in Windows:

Launch the Sound Control Panel applet or select Playback Devices from context menu dynamics, i.e. by right-clicking on it.
If there is nothing in the Playback tab other than the message “No sound devices installed,” right-click there and check the box next to “Show disabled devices.” After this, the unused device must be turned on by selecting the appropriate command from its context menu:

Please note that must be selected correct device default audio output. To set it, just click on it in the list and click on the “Default” button below. Try different ones. You especially need to go here to enable sound output. In addition, by clicking on the speaker marked with a cross, you can start diagnostics and auto-recovery of sound settings:

This built-in wizard also sometimes helps solve the problem.

If the sound still doesn’t appear, let’s check if audio services are disabled:

Defects in system files or registry keys

It will help to solve problems with files and the registry at once if you created a check Point. When there is no point or this function is disabled, you can try to fix the situation using the dism and sfc utilities.

To restore the system to working parameters, run (cmd.exe) and run two commands in turn:

dism /online /cleanup-image /restorehealth

The commands take quite a long time to execute; after finishing the work you need to reboot. They check system files, and if they deviate from the original options, they are automatically restored from storage. During the recovery process you may be prompted installation disk from Windows or flash drive.

Overclocking your computer and resetting the BIOS

Overclocking your computer can cause audio problems. If you or someone else has recently dabbled in overclocking system bus, then you need to reduce the frequencies or reset the BIOS settings to default. To do this, you can use any of the following methods:

1. Go to BIOS Setup and on the Exit or Save & Exit tab, click Load Setup Defaults (Load Defaults BIOS, Load Safe-Fail Defaults, Load Defaults Settings, Set BIOS Default, Restore Defaults - option names in different BIOS versions differ).

2. Find the RTC battery on the motherboard (on boards desktop computers this is a “tablet” CR2032) and remove it from the socket for a while (15 - 30 minutes is usually enough). To speed up the reset, you can briefly short-circuit the socket terminals with the same battery.

3. Find the Clear CMOS jumper on the board (CLRTC, Clear RTC, CCMOS, etc. - on different boards the names, again, are different) and briefly move it to 2 adjacent contacts.

The second and third methods are performed only when complete shutdown powering the computer from the outlet.

Why else might there be no sound?

If the jumpers on the motherboard, which are responsible for reassigning the sound output, are not installed or are positioned incorrectly, then there will be no sound! You need to carefully look at the instructions for the motherboard, the section regarding Audio, and check how the jumpers are actually positioned. In this case, the symptoms are as follows: the file is playing in the player, the volume is set correctly, but there is complete silence in the speakers.

If you are connecting to the front panel, it may simply not be connected to the board or connected incorrectly. There are two types of front panels: legacy AC’97 and HD Definition. Accordingly, if in BIOS settings If there is such a setting, then you need to select the type of your front panel (try both).

If the instructions seem too complicated or the problem was not solved, or when the situation repeats itself over and over again, the best thing to do is contact the service or write about your problem in the comments to the article.

Every modern man owns a laptop, but not everyone knows how to fix problems that arise. Produce do-it-yourself repair not that hard, you just need to know a few things important nuances, which are discussed below. Internet contains great amount queries on the topic of why there is no sound on the laptop. Many people encounter this problem, some of them want to adjust the sound themselves.

Reasons for no sound on a laptop or computer

There is a list of common reasons why the sound disappears. The good news is that most of the problems are simple and can be fixed at home. Every user can liquidate them, even if he purchased his first computer just a week ago. Common breakdowns that lead to this should be named:

the initially implemented settings failed or the sound icon disappeared;
drivers are out of order;
The sound card in the BIOS does not operate in desired mode;
Windows Audio is in the disabled position.

Settings error

This problem is the main reason why there is no sound on the computer. If it happened software glitch, the volume sliders may drop down or a “Mute” checkbox may appear. It is worth paying attention to the settings, because this will solve the question of how to make the sound louder on a laptop. Because of this, the system sound may completely disappear or the volume of your browser may not work. In such a situation, everything looks strange: one gets the impression that the laptop is working in the desired mode, but there is no sound in the browser when watching a video.

Driver corruption

If the volume check has been carried out, all connections are made correctly, but the sound on the laptop does not work, then the cause of the problem may be in the drivers, which are a necessary component for correct operation any computer device. If the driver is broken or operates incorrectly, then sound accompaniment may disappear.

There are main reasons why the driver starts to work incorrectly, among them the following are worth highlighting:

virus programs;
opposition to existing programs;
a failure occurred in the operating system;
problems encountered when updating the driver.

Before you begin to solve the problem, it is worth establishing that the cause is in the drivers. To do this, go to “Start”, then “Control Panel”, then “Device Manager”, go to the “Sound Devices” tab. If yellow is visible in this tab Exclamation point, then this clearly indicates a problem.

Missing or damaged sound card

The laptop may have a completely missing or inoperative sound card, and this may be the reason for the lack of sound. In the "Device Manager" you should refer to "sound devices". Yellow icon indicates that the sound card drivers are out of date or missing altogether. Developed and functioning special programs, which test audio drivers, for example “SoundCheck”, it is worth using it. In some cases, the board will need to be replaced.

How to restore sound?

There is no sound on the laptop, what should I do? Carry out periodic checks, and then, focusing on the reason for the lack of sound, you should perform the following actions:

Reboot your laptop

The first thing you should do in order to restore sound on your laptop is to reboot it. Often after this action the sound appears and everything works as it should. This is especially worth doing if after Windows installations 7 or 8 the sound disappeared. It is necessary that all changes are updated and start working in the new mode.

Check if speakers and headphones are connected

If the reboot does not bring the desired result, then you should check whether the speakers and headphones are turned on and whether the speakers are working properly. There is a possibility of a lack of connection, which resulted in faint sound or he began to wheeze, then it should be strengthened. There are often situations when broken wires cause a problem.

Check your system settings

The situation with system settings not terrible, it can be eliminated quickly without application complex programs. If the sound is missing completely or only in the browser, then initially you need to look at the volume mixer: right-click and go to the phrase “Open volume control.” Next, check the location of the sliders that control the volume state.

If they are located below, then there will be quiet sound on a laptop. They will have to be moved up, the problem of how to increase the sound will be solved. You need to refer to the location of the sound indicators, which should be in the “Turn on sound” position. The slider on the left controls all volume, while the other sliders control system sounds available applications. The indicated problem is actually a common occurrence: if there is no sound, then it makes sense to carefully examine the volume mixer.

Is the sound card disabled in the BIOS?

One of the common reasons why there is no sound on your laptop is that the sound card is not working in the BIOS. This problem can occur after a system failure. In addition, it is possible that the card will be disabled due to the user’s inexperience. It should be said that a non-working sound card is precisely the source of the problem. The solution to the problem is quite simple: you need to go to the BIOS and turn on the card. Immediately after this, the sound when watching a movie should be restored.

Getting into the BIOS is easy; this is done using hot keys that are available on every laptop. After entering the BIOS, you should go to the Advanced Features, Chipset section, then go to “Onboard devices”. On sound card(Realtek Audio, Audio Controller) you need to set the “Enable” icon. The disabled state is indicated by the “Disable” icon. If you go to the BIOS and see the “Enable” sign, but there is still no sound, then another problem should be solved.

Check Windows Audio Services

There is a possibility that the Windows Audio service is disabled in the settings, for this reason the sound will not play. If you do not want to go to service center, then checking the proper operation of this service yourself will not be difficult. You need to press two “Win + R” keys at the same time, a window will immediately appear where you should enter the command “services.msc”.

In this list you should find the “Windows Audio” service and see its status. Correct settings appear when the “Status” column has the “Running” mode, the “Startup Type” column is set to “Automatic”. When the “Status” field is set to “Stopped,” this indicates that the service is not running, resulting in no sound on the laptop. You need to go to this service and select “Start”.

Update your drivers

To update, you need to go to the device manager where the sound card is, right-click on the “Properties” tab. A window will appear in which you should find the “Driver” tab and click the “Update” button. Next, a method of searching via the Internet will be proposed. If you have a disk or folder with drivers, then you need to select the second option and indicate the location where the driver is located. If there are no drivers, you should download them from the Internet online.

System rollback is another possible option solving the problem. It should be carried out if it is related to incorrect update drivers. This is easy and quick to do; you just need to click “Roll Back” and click “Yes” in the warning. If the loss is due to incorrect operation of the sound card driver, then you should figure out how to configure the necessary parameters yourself.

Video: what to do if there is no sound on your laptop?

In order to solve problems with sound on a laptop, you should rely on the experience of more advanced people who have already carried out repairs with their own hands. The video will be your visual aid and will allow you to do everything quickly and accurately, since it discusses significant options and solutions that, by the way, are available even to novice users. Why is there no sound on my favorite laptop? Watch and act, everything will definitely work out.

When faced with the problem of a sudden lack of sound on a laptop, whether it has Windows 7 or Windows 8 installed, you can easily get confused in identifying the causes of the unpleasant incident. Below we describe in detail the main cases due to which the sound on the device may disappear, as well as methods for solving them.

In order to make it easier to deal with the problem, it is necessary to divide all options for missing sound into two main sections.

Reasons why there is no sound

First of all, the laptop may stop reproducing any information:

after reinstalling Windows;
and completely suddenly.

The second point raises a fair amount of doubt, but it can also be solved and, in the end, explainable.
In fact, nothing “sudden” a priori happens. This means that it is logical to identify more sub-items to clarify the reasons.

Reason 1. Simple. The volume on the gadget is turned off;
Reason 2. Complicated. The sound output device is not designated by the device as the main one;
Reason 3. Functional. Uninstalled audio codecs;
Reason 4. Fundamental. Absence or incorrect operation of sound device drivers;
Reason 5. Conflict. “Rivalry” of some drivers with others;
Reason 6. Built-in. Disabled sound card in BIOS settings;
Reason 7. Complex. The sound output device is not working. These could be speakers, headphones, or the sound card itself.

In addition, it is worth adding that the lack of drivers is the most common reason just after reinstalling Windows.

Eliminating the causes

And although a cumbersome list has the ability to inspire fear and horror of irreparable damage, it is countered by another - a glorious list of eliminating the above-mentioned causes.

So:

Checking the Audio Control Service

We should also talk about Windows Audio, or the Sound Control Service. It did not appear on the list of reasons why the laptop stopped playing audio, since it is part of most of them.

The Audio Control service is rarely disabled, but the definition of “rarely” has its exceptions, which means it should be checked, especially if other options have failed.

In Windows 7, in order to check whether Windows Audio is enabled, you need to:

Windows 8 differs little from its predecessor in these parameters, but it is fraught with both an assistant and several pitfalls. Why doesn't the sound work? Windows laptop 8? And why deal with the problem in this operating system will it be easier and more difficult at the same time?

First of all, the “eight” will warn you in advance about disabling the Audio Service using error 1068, so you won’t have to guess whether Windows Audio is to blame for what happened. The pitfalls are that the Sound Control Service depends on three other services at once, therefore, disabling at least one of them will inevitably lead to problems.

Responsible for the sound:

Media Class Scheduler;
Windows Audio Endpoint Builder;
Remote procedure call (RPC).

Why doesn't the sound work on my laptop?

They did everything, connected everything, but for some reason there was no sound. Why?

For example, the browser settings are responsible for the sound on the Internet (although sometimes it’s enough just to restart it), and why the sound in Skype on a laptop does not work is easy to understand if you realize that the laptop settings Skype settings are weak.

Therefore, all you need to do is:

log into your account and set the correct playback parameters;
connect speakers and a microphone and enjoy the wonders of civilization.

Checking for driver availability

Let's also say a word about drivers. After all, the fact that the problem arose definitely because of them gives only a few more branches to its solution.

The missing driver can be downloaded from the Internet or purchased from any other (necessarily reliable!) source. The trick is that there are many options for which driver is not available: both sound output devices and devices for related services. If you couldn’t find it right away, you’ll have to check everything;
Sometimes drivers just need to be updated. Again, either all or only some;
If the drivers have already been reinstalled, the wrong version may be installed.

Conclusion: in this case, a reliable assistant is a scrupulous check.

Audio system connected correctly

An audio system that was installed and connected incorrectly may cause the sound on the speakers to disappear without a trace.

Actually, in order to check whether everything was done correctly, you will have to go through the instructions again and check whether the correct connectors were selected for connection. In addition, until the audio system is configured correctly, it will be impossible to select five-channel sound in the sound settings.

Note To play five-channel audio, you will need the appropriate file format.

Sound settings

They adjust the sound on the laptop using the menu of the same name, which can be found without even going to the Control Panel, but simply by entering “sound” in the search (Start - Find).

The tab that opens provides options for setting parameters for sound devices. It is important to ensure that they are all connected and provide optimal volume.

No sound in headphones

“The sound in my headphones doesn’t work,” the user complains. So what should we do?
If playback becomes silent when you're wearing headphones, the first thing to do is check to see if the sound is lost only on them.

If the answer is “no”, the options are outlined above, the answer “yes” implies that the device is definitely connected correctly (at this point it is better to make sure of this).

Headphones can be broken, that's a fact, but there can be a very common problem as follows.

The so-called HDA controller, which for some reason desperately interferes with the joy of weekdays - headphones. If there is a device that supports it (look for it in the Device Manager), then delete both it and the controller itself, and after a reboot everything will return to normal.

The sound control function (key) does not work

The Fn key combination and the speaker icon in the top row are responsible for controlling the functions of muting and unmuting the sound. F8-F12 on the keyboard (each laptop model may have its own mute key), and if it stops working as expected, it means there have been problems with the hotkey settings and keyboard connection.

The problem is solvable system file HControl (Path C:\Program Files\Asus\ATK Pakage\ATK Hotkey). After launching it, the functions are restored and the sound control key combinations can be used again.

But this solution is, so to speak, generalized, more special case when Fn sound does not work on Windows 8. Unfortunately, this happens everywhere.

Sometimes under the desired model The laptop has not yet released drivers for this operating system, and then you will have to be content with manual control.

The second option: incorrect installation of Windows 8 itself, which means the solution will only be available after a restore or reinstallation.

Responsible for playing sounds in a laptop:

multimedia services;
BIOS;
embedded devices;
connected devices;
OS;
and, ultimately, the whims of technology.

Without identifying the reasons, the problem cannot be solved. But this does not mean that it cannot be solved; specialists will help you set up sound in Windows 7 and 8.

On modern computers A very common problem is that the sound on the laptop has disappeared. We’ll look further into what to do if this happens. In fact, there are not many reasons why this happens. Moreover, they are the same for various models laptops - HP, Lenovo, Acer and others. So, let's start with the simplest thing.

Settings failed

This problem is that for some reason the sound level is reduced to a minimum or completely turned off. Moreover, this may not affect the entire system as a whole, but only the browser or system sounds. There are a huge number of reasons for this phenomenon. The main one is carelessness - the user, due to inattention, can press the volume reduction buttons on his laptop. On the other hand, this could also be the work of some kind of malicious program, so checking the entire system using an antivirus would not be a bad idea.

As for solving this problem, everything is done extremely simply. Specifically, you need to do the following:

In the panel quick launch Right-click on the volume icon (highlighted in Figure 1 with a red frame). In the drop-down menu that opens, select “Open Volume Mixer” (highlighted in green).

After this, the window shown in Figure 2 opens. If we see a muted icon there (an example of this is highlighted in a red oval), we need to click on it, after which the sound will return to normal state. In general, you need to raise the volume sliders (highlighted with a green frame).

As you can see, the volume mixer window displays all the sounds that are on this moment only available in the system. The first column is responsible for almost all sounds that come from the speakers. The second column is responsible for system sounds. These include the sound of a window closing, error sounds, and the like. Finally, other bars may appear depending on running programs. For example, in Figure No. 2 there is a column with Opera browser. It appears only if you watch a video in it or do some other operations in which the presence of sound effects. In the place where the browser appears in our example, there may be some kind of game or other program currently running. In general, the first thing to do when audio is missing is to open the mixer, move all the sliders up, and check to see if the audio icons are muted.

Driver failure

As you know, in order for hardware to communicate normally with software, drivers are needed. They serve as a kind of translator between these two important components of the computer. But drivers, like everything else in this world, are imperfect and can also break. IN in this case we're talking about about the device that is responsible for supplying sound signals, that is, about the sound card. It is its drivers that may stop working altogether or start working incorrectly. There may be several reasons for this phenomenon, the most important of which are as follows:

A virus gets onto your computer (again, we return to the fact that you need to check your laptop for viruses using an anti-virus program);
Incompatibility of installed programs;
Just some kind of glitch software;
Problem during update - old driver has already been deleted, but the new one has not yet been installed, and there is simply no one to service the sound.

As mentioned above, these are just the most common reasons. In fact, there can be quite a lot of them. But in this case (and this rarely happens when working with computers!) there is no need to look for a problem at all. The solution to the problem is to update the sound card drivers.

Driver update process

To update your sound card driver, you need to do the following:

Open the Start menu and find “Control Panel” there. Figure No. 3 is relevant for the Windows operating system. In others Windows versions this item can also be located in the Start menu, or maybe right on the desktop or in other places. In any case, all versions of Windows have a search where we can enter the query “Control Panel” and easily find what we need.

Here in the search bar you should enter the query “Device Manager” (shown in red frame in Figure 4). You can also find it in the list that opens without any searches. In the resulting list, you must select “Update device drivers” (underlined in the same figure with a green line).

This will open the Device Manager. In it you should select the item “Sound, video and gaming devices” (underlined with a red line in Figure No. 5). This is very easy to do - click on the icon for opening a list of such devices (highlighted with a red oval). Next, a list of all available sound devices will open. By the name you can understand which of them are responsible for the sound - the word “Audio” will appear in the name. Although, to be on the safe side, it is better to update the drivers of all devices presented in this list. To do this, right-click on each device and select “Update drivers...” from the drop-down menu (circled in green).

Now we have two options available to us - automatic search drivers on the Internet or selecting a driver file yourself. The second option assumes that we have already downloaded the driver for this device in advance or inserted a disk/flash drive with it into the computer. But in most cases, we still have to look for them on the Internet, so we choose the first option.

After this we will see the process of searching for the required program.

After this, the system will display a list of available drivers. The user will only have to select one of them by simply clicking on it with the left mouse button. Next, the installation process itself will begin. Although the system may display a message stating that “the drivers for this device do not need to be updated.” Then you just need to close open window update and move to another device.

Disabling the Windows Audio Service

In the operating room Windows system There is such a simple system as Windows Audio. She actually does it quite well. simple function– providing sound. In general, Windows has a lot similar systems and then we will be able to see their entire list. In any case, Windows Audio may turn off, and the reasons for this are exactly the same as before - carelessness or inexperience of the user, work virus programs and so on. This problem can be solved very simply. To do this you need to do the following:

Press the Win+R key combination on your keyboard to launch the program execution window. In the window that appears, enter “services.msc” and press on the keyboard Enter key or the “OK” button in the same window (highlighted with a red oval).

Everyone window opens Windows services, including Windows Audio. Actually, we need to find it in all this diversity. Right-click on it and select “Run” from the drop-down menu.

Note: In Figure 9, the “Run” command is inactive, because the serviceWindows Audioworks fine. If there is no sound on the laptop and the “Run” command is inactive, then the problem is not with this service. Otherwise, it will be active and the service can be started.

Sound card turned off

Sometimes a phenomenon may occur that the sound card simply turns off and turns off. And the reasons for this are still the same, but most often it is disabled due to a software glitch. Without going into details, let's say that the solution to this problem is very simple - enable the sound card in the BIOS. The main difficulty is to enter this same BIOS at all. The main problem is the different way to login to different brands computers. We will look at how to enter BIOS on different brands of laptops later. Let's imagine that we have already gotten there. Now you need to understand what to do next.

And after we got into the BIOS, we need to find an item that is somehow related to sound. You can also recognize it by the word “Audio” in the name. In some cases, the title will include the word “Sound”. Examples of such names are as follows: Realtek Audio, Audio Controller, Onboard Sound, HDAudio. The latter can be seen in Figure No. 10.

Accordingly, you need to click on this item and select the “Enabled” option. In the above option, this option is already selected, but in the event of a breakdown in the sound card connection, another option will be selected. That's really all we need to do.

How to get into BIOS

In fact, how to get into the BIOS is already written in the boot screen. You can find an example below.

As you can see, it says that to start the installation you need to click Delete button on keyboard. It is also possible to press the F2 button. In general, all information on this matter can be found in the loading screen. To get into the BIOS, you need to press the indicated button until it loads into the BIOS.

Now the problem is that, again, depending on the laptop model, the interface can be completely different. This is what a classic AWARD BIOS looks like. The interface is very old, as it seems at first glance.

This is what the AMI BIOS looks like, which is also quite familiar to many at least somewhat advanced users.

Here is the most advanced interface that UEFI BIOS users can see today. In general, here the creators decided to move away from the canonical forms of AMI and AWARD.

What do we need to find in this most terrible BIOS for many users? Here we need a section that is responsible for the operation of built-in devices. Again, it will be called differently depending on the model. Example names: Advanced Features, Chipset or Intergrated Peripherals. In any case, you can understand from the meaning what this section is. For example, in the same AMI BIOS the corresponding menu item is located where the arrows point in Figure No. 15.

So we need to go there. And there we can already find those menu items that are shown in Figure No. 10.

Results

To summarize, we can say that there is definitely no need to panic if the sound on the laptop is lost. As we see, possible reasons There are very few such phenomena here, and the solutions are all very simple. By the way, if they don’t help, most likely the problem is in the sound card itself and it’s best to simply change it.

Advice: Do all the above steps twice just in case. The fact is that inexperienced user may make some error when working with BIOS and device manager.

The method associated with the device manager is clearly shown in the video below.
