What to do there is a sound. The sound on the computer does not work, what should I do?

Owners of laptops from Asus, Acer, Samsung, HP and other models encounter a variety of audio problems during operation. In this article we will look at why the sound on the laptop disappeared, what to do and how to correct the situation. Don’t rush to call the technician or run to service center, often the problem is solved with your own hands.

The reasons for the loss of sound from a laptop are varied, but they can be divided into 2 areas: software and hardware. The problems discussed and solutions in this manual mostly relate to software, since they are more common than hardware ones and can always be fixed.

Changing the volume level and status indicator

The first step is to check for muted status in the volume mixer. You can recognize this by the red crossed out circle on the volume icon, but not always. Users randomly or due to system glitches turn off the sound on their laptop. The following situation may exist: complete disappearance of sound or partial (in applications). To view and change the volume scale, follow these steps.

In the system tray, right-click the volume icon. From the menu, select "open volume mixer". If you do not see this element, read the instructions on why the volume icon disappeared from the taskbar in Windows.

In the volume mixer you will see two areas: “device” and “applications”. The “device” area controls the sound of the laptop speakers. In the “application” area, system and application sounds are regulated. Each element has a volume slider and a status indicator. If the indicator has a speaker icon with a red crossed out circle, then left-click on it to set the “sound on” position. If necessary, adjust the volume sliders to an acceptable level.

If there is no sound on the laptop in a separate program, then launch it, after which it will appear in the volume mixer in the “applications” area. Switch the indicator and adjust the position of the slider. The screenshot below shows an example with the Yandex browser.

Don't forget to look at the settings or volume indicators in the programs themselves. For example, in browsers the sound is still regulated Flash player, where there is also a volume slider and an icon complete shutdown sound in the player.

Laptops have shortcut keys for controlling overall audio, so you don't always need to visit the volume mixer. To turn on the missing sound, hold down the Fn button and press the button with the crossed out volume icon or similar (usually located in the top row of the keyboard). You can also hold down the Fn key and press the volume up key with the volume icon (usually located on the keyboard arrows, next to the buttons). See the screenshot below for the hotkeys. Acer laptop.

When there is no sound on your laptop, first follow the steps above. If the problem persists, restart the laptop, as long-term operation may cause a system failure and after restarting the system, performance may be restored. Read on if the recommendations above do not bring success.

Reinstalling sound drivers

If the volume settings are fine, then there may be a problem with the sound drivers. If the drivers fail or are unsuccessfully updated, the sound on the laptop disappears. To restore them, consider reinstalling and rolling back sound drivers.

Open Device Manager. Enter the command devmgmt.msc, then click OK. In Device Manager, expand the sound devices item (see screenshot).

If your audio device is not working properly, it will have a small "!" or "?" icon. Double-click the audio device to bring up the properties window. Visit the “driver” tab, click the “update” button.

In the open window, select automatic search drivers. If drivers are found, they will be downloaded and then installed automatically. If the OS did not find the driver, then read on.

Pre-download a set of sound drivers from the laptop manufacturer's website or a third-party resource. The most common audio device manufacturers include:

1. Realtek
2. Creative
3. Logitech

Many driver packages have an installer. By installing this software, you will automatically install the driver, thereby restoring sound on your laptop. Next, you will need to reboot the system.

If you have a set of drivers without an installer, then in the properties of the audio device, when you click on the “update” button, select search and install drivers manually (second point). Specify the folder, click “next” and wait for the installation process to complete. Next, you will need to restart the system. More detailed information Read the recommendations on how to install drivers on Windows.

After failed update drivers You may notice that the sound on the laptop has disappeared. The reason may be that the new driver is damaged or incompatible. In this case, clicking the “roll back” button will help you (returns previous version driver) in the audio device properties window. Click “yes” in the message.

Enable the audio service

It happens that the Windows Audio service, responsible for sound playback, has stopped. The volume tray icon has a red circle with a white cross. When you hover over the volume icon, a hint pops up that the audio service is not running. To restore sound on your laptop, you need to left-click on the sound icon. Then the troubleshooting wizard will automatically fix the problem, and you will see that the red cross icon has disappeared.

You can start the audio service manually. Press the Win + R button, copy services.msc into the input field, then click OK. Sort the services by name, then find the Windows Audio service, double-click on it with the left button.

On the "General" tab in the properties of the sound service, set the startup type to "automatic". Next, click the “run” button and wait a bit. Now the missing laptop sound will be restored.

Other ways to restore sound

There are many reasons why sound disappears. These reasons can be varied, so it is not always known why the sound on the laptop disappeared and what to do to restore it. Here are some recommendations that may help you:

1. Run the troubleshooter to help fix common audio problems.
2. In the sound settings, set your audio device as the default playback device.
3. In Device Manager, enable the audio device.
4. and turn on the audio device there.
5. Update your BIOS.
6. Make sure that the external speakers and headphones are in working order, and also make sure that the plug is plugged into the line output.
7. Install OS updates.
8. Do a system restore.

You can consider some of the recommendations above in more detail in the article, the sound on the computer does not work in Windows 7, 8, 10. Now you know why the sound on the laptop disappeared, what to do and how to restore it. If you have tried all the methods and your audio device still does not work, most likely the problem lies in the hardware. At home, a full-time user cannot fix problems with equipment, so a trip to the service center is indispensable.

Quite often, users encounter the loss of sound on a computer running Windows 7. There are many reasons for this. Some are quite simple. And sometimes it takes several days to find a problem. This short review is dedicated to how to find and fix the breakdown.

Non-working speakers

Let's consider possible options breakdowns:

These measures are basic, but you shouldn’t forget about them. If the check didn't yield anything, then it's time to move on.

Hardware audio settings

After obvious faults have been checked, you should pay attention to the software sound settings. It is quite possible that the sound in Windows is turned down or completely turned off. If it is reduced so much that it is barely audible, then the user will most likely assume that the computer itself has broken down.

It’s best to see visually how the sound is adjusted at Windows example 7, on Windows 8 and 10 the principle of operation is the same:

Let's look at the functions of the window that opens in more detail:

If you are unable to play the test sound, you should check to see if the sound is turned down to the minimum value or turned off altogether:

Check Device Manager

If there is no sound on the computer under Windows control 7, as well as operating systems Windows 10 and other versions, you should check the status of mini-programs (drivers) for sound card. Most likely, they need to be updated or they are not there at all.

You can check the status of the equipment and its drivers in “ Device Manager", which is easy to find in Control panels on the " System».

Systematically displays all devices that are present on a computer or laptop, as well as the status of their drivers. If a yellow triangle is lit nearby, you should pay attention to it first. This means that the sound card is not working at all or is not working correctly. In our case, we are interested in the item “ Sound, video and gaming devices».

If a problem is identified due to which the sound does not work, you need to download and install a driver that is compatible with this PC. You can keep your computer up to date using special utilities to automatically update and search for the latest version of drivers for any equipment on a PC or laptop. For example, the program Everest will determine the sound card model, check all drivers for relevance and tell you where to find the necessary drivers for sound on Windows 7.

When you monitor the current state of your computer and carry out regular updates, you may encounter the problem of no sound during the next automatic driver update. The source of the problem may be an updated driver. "" will help restore the working situation. On the " Driver" his sound card you must click the Rollback button.

If the problem disappears, it is better to disable automatic update drivers for this device.

Updating drivers in Windows 10

The algorithm of actions consists of the following steps:

No codecs for audio/video

If there is sound in the browsers, but there is no sound when you start the video on the PC, then you should look for the problem either in the media player itself or in the audio codecs.

To constantly watch videos, it is recommended to use KMR player. He has already proven himself and is showing good results. The creators of the program have provided a lot of different codecs for video playback. And, as a rule, most films are successfully reproduced in this program.

The problem with codecs can be radically solved using the package K-Lite Codec Pack. It can solve the missing sound problem. It has a full set of current codecs that open almost all popular formats, both video and audio files.

Viruses and adware

Problems with sound on Windows 7 may mean that a virus has appeared in the system. There are many types of viruses and they can negatively affect the operating system.

How to behave if the sound on your computer disappears and you suspect a virus:

• Take a close look at how your computer works as a whole. If it often freezes or slows down unexpectedly, then most likely the PC has undergone a virus attack. If installed antivirus program failed and missed the virus attack, then it is best to check the system with a third-party antivirus with up-to-date virus databases. For example, you can use the utility Dr.Web CureIt. This healing utility successfully cures an infected system.
• You can try checking your computer using Live CD(emergency boot disk). With its help, you can download a lightweight version of the operating system with a ready-made antivirus. If you boot the restored system from Live CD sound appears, then most likely there is a malfunction in Windows 10 itself. Most often, you will have to reinstall it or perform a system restore using restore points, if this mode was enabled and restore points were created.

Checking the BIOS settings

If your computer or laptop has a built-in sound card and there is no sound even in headphones, then you can look BIOS.

This is an extreme measure - AC97 is enabled by default in the factory settings. If the settings are lost, then the sound device in the operating room Windows system won't work.

Each computer logs into the BIOS differently. For example, for ACER computers, before booting the system, you must press and hold the Del key. In general, before loading the operating system, you must indicate how to enter the BIOS.

After pressing the Del key, the following dialog box will open, in which you need to select the item “ BIOS Setup».

In the window that opens, you need to find an inscription like AC 97 Audio, use the arrows on the keyboard to highlight this inscription and click on the Enter key. A dialog box will appear to select which function to activate HD Audio or AC97. We are interested in the AC97 “Auto” inscription. Confirm your choice and use the ESC key to exit this section. Exit the BIOS, saving the settings.

If you can’t get the sound back after changing the BIOS settings, then the last option is to replace or send the sound card for repair.

Laptop owners often encounter the problem of no sound in the Windows system. Due to frequent overheating of the sound chipset, the computer begins to malfunction. And all the rest of the electronic stuff simply suffocates with dust, unless, of course, you do regular cleaning, and gradually breaks down, which can also lead to loss of sound on the laptop.

Conclusion

Of course, these are not all the reasons why there may be no sound, but the main, most common versions are revealed.

So, we told you how to restore sound in Windows 10, 7 and 8. And our main advice is not to despair, but to try all the options step by step.

Video on the topic

A computer is a very complex multifunctional device that likes to pull all sorts of tricks at the most inopportune moment: either the video card will fail, or south bridge burns out, then for no reason the sound disappears on Windows 7 or some other operating system. Even an ordinary user needs to know everything about how to deal with these troubles. The most common problem is sound failure after the next system update or for some other unknown reason. But in order to competently solve this problem, you must first determine what went wrong and identify the primary source of all troubles. This is what will be discussed in this material. So, how can you give your computer its voice back? Let's try to figure it out.

Reasons for no sound on the computer

There are several reasons why your computer may lose sound. All of them are divided into hardware and software. If the problem is hardware in nature, then there is a very high probability that an adapter will be required. If the problem is of a software nature, then you can get by with “little loss” and on your own. If the sound disappears on Windows 7 or some other version of the OS, then the first thing you need to do is check all the connections and the functionality of the speakers or headphones. If the problem is not solved, check the availability of drivers for the sound card. If everything is fine with the drivers, then you need to check the sound adapter for functionality. And if this doesn’t help, we check it for hardware damage.

Hardware problems are the most difficult. If the user has a full-fledged computer with a system unit, then replacing the sound card will not be difficult. And if you only have a laptop or PC that uses a built-in sound controller, then you can’t do without a trip to a specialist. In any case, you will have to spend some money on professional help or a new sound card. This is the main trouble with hardware sound problems. So, the sound on the computer disappeared. How to restore it? Let's take a closer look at the most popular methods.

How to fix? Method 1: attentiveness test

Often, inexperienced users simply do not notice that the system is set to minimum or the sound is completely turned off. To eliminate this problem, just look in the system tray - at the volume icon (speaker). If it is crossed out, then the sound is simply turned off. To turn it on, click on the icon and click on it again. Then the sound should appear. If the icon is not crossed out, it still makes sense to look into the tray and move the volume control to maximum. This, by the way, is also the answer to the question of how to increase the sound on a computer.

If after carrying out all the above manipulations nothing happens, then the problem may be with the speakers or headphones. Make sure that acoustic system plugged in and turn the volume control to maximum. After that, play a song on your computer. The sound should appear. If this is not the case, check the connection between the speakers and your computer or laptop. Sometimes someone can swap the plugs without your knowledge. If everything is in its place, but there is no sound, then the problem is much more serious than it seemed at first glance. Now we will seriously understand why the sound in the computer disappeared and how to restore it.

How to fix? Method 2: Enable the sound device

Setting up sound on Windows 7 is not such a difficult task. However, before you move on to tinkering with drivers and other software, you need to make sure that your standard audio device is enabled and in use. It's very easy to do. Go to "Start" - "Control Panel" - "Device Manager". There we look for the name of our audio device and see which icon is next to it. If the arrow is gray, the equipment is disabled. To enable it, you need to do the following manipulation: right-click on the device and select “Enable” in the menu that appears. After this, a sound should appear. If the sound on your computer has disappeared and you don’t know how to restore it, then the following chapters are just for you.

But sometimes this doesn’t help either. So, the sound on the computer disappeared. What should I do if everything in the place of the audio device in the “Device Manager” is completely empty? This happens after someone has removed the device along with all the drivers. To fix this, you need to restart your computer. The system itself will detect the new device and try to install the necessary drivers. But! Even if this option works, you can’t count on the system drivers being up to date, which smoothly moves us to the next chapter of the material: installing drivers and other software.

How to fix? Method 3: drivers

Often the lack of sound on a PC or laptop results in software problems. The most common of them is the lack of necessary drivers in the device’s operating system. It’s very easy to check: go to “Control Panel” - “Device Manager” and look at the section with audio devices. If there are yellow question marks instead of icons, then there are definitely no drivers. Therefore there is no sound. What to do? If there is no sound from the computer speakers due to drivers, you need to go to the official website of the device manufacturer and download the latest utilities. You can, of course, try to update them with standard Windows tools, but the Microsoft servers have quite ancient versions. So it's better to download it yourself.

Sometimes, instead of a yellow question mark, in place of the device you are looking for in the “Device Manager” there may be an inscription like “Standard audio device”. Don't rush to rejoice. This also means that necessary programs no, which means the device may be unstable. With various tricks and glitches. Therefore, drivers must be installed in any case. This will have a positive effect on the overall speed of your PC or laptop. Just remember that after installing the drivers, you need to restart your computer. If even after installing the necessary software, sound playback on your computer does not start, you need to prepare for the worst.

How to fix? Method 4, hardware

If you have a standard Personal Computer with a system unit, then there is a high probability that you are using a separate sound card. What to do if there is no sound on the computer? How to restore it? There may be some kind of hardware failure in the sound card itself. You need to remove it, then put it back and turn on the computer. The chances are, of course, slim, but sound may appear. If it does not appear, then you need to determine for sure that the audio card is to blame. To do this, you need to take a known working card from your friends and insert it into the connector of your motherboard. If sound appears, there is a problem with the card. If not, the problem is with the motherboard. And both of these components will require replacement.

If you have a laptop or computer that uses a sound controller that is built into motherboard, then things are much worse. So, the sound on the computer disappeared. What should I do if there is a hardware problem in the controller that is built into the motherboard? There is nothing you can do here yourself. You will have to take the computer to a service center where there are professionals with the most modern equipment. As a rule, you won’t be able to determine that the problem is in the 3.5 mm mini-Jack jack (if there is no sound in the headphones on the computer). Therefore, you cannot do without a trip to a specialist, although you could change the nest yourself.

Why is there no sound when watching a video?

Sometimes it happens that there is no sound when watching a video on a computer. The most common reason is a video player that lacks codecs. Usually the standard player from Microsoft suffers from this. Everything is simple here. There are only two options: either install new codecs, or change the player. The latter, by the way, is preferable, because the standard player cannot do much of what modern free utilities are capable of. The best one today is Daum PotPlayer. It plays everything and videos without any problems. It also has an impressive library of built-in codecs. And this is important.

However, it also happens that when watching a video, the sound on the computer disappears. What to do if everything is fine with the player and codecs? The player may be using the wrong audio output device. You need to go through the settings and make it play sound through standard device, which should be installed by default. Each player has its own settings tree, so there is no way to describe the process of changing the output device step by step. Here you need to act using the “scientific poking” method. But finding these settings will not be difficult. Moreover, most video players now support the Russian language.

Improved sound quality. Method 1, software

It also happens that the sound quality noticeably decreases after any actions in the computer operating system. There may be crackling, noise, tunnel effect and other interference. This must be due to the recent installation of some program that managed to somehow affect the sound quality in the PC or laptop. The sound volume on your computer may also be affected. The easiest way to fix the situation is to remember which program you installed and uninstall it. After this you need to restart your computer. If this method does not work, then you need to use “System Restore” from the “Start” menu and roll back the operating system to the time when everything was fine with the sound.

Some users want to make their computer sound better. There are several products that will help implement this idea. The most best program for sound on a computer - SRS Premium Sound. It has a huge number of settings and a bunch of effects that will help improve the sound quality on your computer. And although its interface is completely English language, no one should have any problems with it, because it is simple and intuitive. This utility“settles” in the system tray and improves the sound of a PC or laptop in real mode. However, there is one drawback: the program is not free. And the trial version is very limited in customization options.

Improved sound quality. Method 2, hardware

No matter how advanced the computer audio program is, it is not capable of improving the sound beyond the limits of the sound card. And here the problem of the hardware capabilities of the audio chip appears. But she also has a solution, albeit a rather expensive one. You can purchase an external DAC that will provide highest quality sound. But there are some nuances here that could lead to the rejection of this option. Firstly, a DAC is quite expensive. Not everyone has the opportunity to purchase it. Secondly, you need a receiver (aka an amplifier), because without it you cannot connect a good speaker system (or headphones) to the DAC. But if you listen to it on office tweeters, there will be no difference.

From the above thesis, the need to purchase logically follows. This, by the way, will also be the answer to the question of how to increase the sound on a computer. Because a good amplifier coupled with a high-quality speaker system is quite capable of coping with this task. But that's not all. Ideally for high-quality sound I need an almost silent computer. The best option is a laptop or ultrabook. Standard system units buzz too much. But this is no longer necessary. A high-quality DAC and speaker system or headphones of the appropriate class will be sufficient. This will help take your sound quality to the next level.

How to increase

Sometimes it is vital to know how to increase the sound on your computer. This is necessary in cases where the laptop's built-in speakers are not capable of delivering many decibels or there is a speaker system without a volume control (or it does not work). This can be done using special programs (SRS, Realtek Audio) or by selecting frequencies. It's no secret that equalizer settings can have a great effect on sound volume. So it makes sense to play with the sliders and find the optimal one for yourself or your PC.

Conclusion

So, now you know what to do if the sound on your computer has disappeared and how to restore it. There are two types of reasons why this problem can occur: hardware and software. While software problems can still be dealt with on your own, hardware problems can often be unsolvable. Only a trip to a service center for PC and laptop repair will help here. There are specially trained people with the right tools who can get your car in order in the shortest possible time. There is no point in trying to fix a hardware problem yourself. Other computer components can be damaged. And their repair can be very expensive. Therefore, it is better to trust the professionals. And you can play with drivers and all sorts of programs to improve the sound as much as you like. They cannot cause physical harm to the sound card.

If you have lost sound on your computer, then this is of course very bad; you need to figure out why this happened as soon as possible and quickly solve this problem.

The reasons for the sudden absence of sound can be very different, it can be anything at all, so we will look at the 10 most popular reasons. They are suitable for almost any Windows, from xp to 10, including windows 7 and 8.

I will immediately ask you, please take your time before writing in the comments saying what to do, I have no sound on the computer, nothing helps at all. First, consider and work through all 10 steps, I am 99 percent sure that the devil lies in one of the reasons listed.

What to do if there is no sound

Let's start, as usual, with the simpler ones, and end with the more complex ones.

1. Volume controls

Notice the volume icon in the notification area and click on it.

Naturally, the volume slider should be at least in the middle. Make sure it's not at the very bottom.

Well, if the volume icon has a prohibitory icon like this, it means that the sound in the system is completely muted.

Click on it and the sound will appear again.

Here we should also have everything inclusive.

If suddenly one of the sliders is at the very bottom, then move it at least to the middle and then the sound from the speakers will appear.

Don’t forget to check the sound on the speakers, make sure that there are no headphones inserted into them; if they are, then you need to take them out.

And so we continue to look for the answer to the question, Why did the sound disappear on the computer?

You need to go into those devices that are different and check.

Click the volume icon and go to .

In the program that opens, find your speakers in the list of devices and check that there is a green checkmark there.

If God forbid it is not there, then you need to right-click on the device and select Use as default.

If your speakers are highlighted in gray and the status is Disabled then it's easy to fix. Right-click and select turn on, of course Don't forget to make them default.

It also happens that our speakers are not here at all, they are not displayed, in this case you need to click on an empty space and select Show disabled devices. The speakers will then be displayed and they can be turned on as I wrote above, and then set to default.

3. Check your sound card

You need to be sure that the sound card is turned on; if there is still no sound in the speakers, then this point also needs to be checked.

Perhaps it has already been turned on, or maybe it is not here at all, there are different cases if your sound card is not displayed, but there is a section for other devices, for example, audio devices on the bus, and next to it there is a yellow exclamation mark.

This means that the driver has crashed and needs to be reinstalled. I will talk about this in the next paragraph.

4. Check the drivers for sound (Important!)

If you suddenly determine that the sound on your computer has disappeared due to the lack of a driver, then you naturally need to reinstall it.

But for those who have this driver, I still advise you to install it, since most likely previous version is already outdated and will be updated with a more recent one.

1. First, let's decide which driver we need to download.
2. Let's go back to Device Manager and double-click on the sound card.
   
3. Go to the tab intelligence, find the section properties and select an item from the list Equipment ID and several values ​​will appear, we will need the first one first. Copy it.
4. Next, go to the website devid.info, enter this value into the search bar and click Search.
5. This site will select the most suitable driver for us and all we have to do is download the most latest version for your operating system.
   
6. After downloading the driver, run the installation file if available.
   
7. If the driver was downloaded in some other format, then it is installed a little differently, you need to use the task manager, click on the Driver tab Update.
   
8. After that, search for drivers using the built-in program.
   
9. Click browse and indicate the path where the driver is located. Click next.
   
10. The installation will be completed and the driver version will be updated upon completion.
    

But installing a driver for sound is not all.

For those who have a sound card Realtek, and almost everyone has it, I recommend installing an auxiliary program.

It's called RealtekHigh Defender Audio Driver. It helps a lot when working with sound. If, for example, the sound on the computer disappears, then again after installation Realtek High Defender Audio, the problem can most likely be solved.

Download Realtek and install.

The installation takes place in two stages, first the program copies necessary files and warns that the computer will be rebooted, and after the reboot the driver fully continues its installation.

Once the installation is complete, the computer will need to be restarted again for all the changes to take effect.

As a result, we will see next to the volume control new icon, this is a small column that indicates that the program is already running.

You can run it and you can even make some settings, but more on that in the next article.

5. Connection to a computer

If the sound still doesn’t work, then here’s another reason that comes up from time to time. Here is his solution.

Expand system unit and check that the speaker cable is completely inserted into the appropriate connector.

It's almost always highlighted green, this is the speaker jack. Check that the cable is firmly inserted into this connector. And in general, to be on the safe side, I advise you to pull it out again and reinsert it again.

6. Windows Audio Service

Sometimes it happens that the sound disappears due to a service failure. Let's check that everything is okay there.

7. Checking the speakers

Of course, you have already checked 100 times, turning the volume controls on the speakers, but I cannot skip this point, since it happens that somewhere the wiring has come loose, they forgot to insert the speakers. Or let’s say the headphones are broken and the like. And the user immediately panics, what to do, there is no sound, what happened.

Connect the speakers that have no sound to another computer or laptop. This will be much more reliable; if you do this procedure, then you will be 100% sure that your speakers are not broken, it will be much easier. The same applies to headphones, if there is no sound there either.

8. Setting up sound in BIOS

This step is for those who have recently made some changes to Bios. If you changed something in Bios, then there is a chance that you accidentally disabled the function that is responsible for sound.

9. Viruses

If you have some kind of hard virus, then it is 100% that it harmed our computer.

You need everything malware delete. Well, of course, the sound rarely disappears due to viruses, but this also happens, so this step also needs to be worked out

10. System recovery or reinstallation of Windows.

If you suddenly lost sound on your computer or laptop, and you even know what day it happened or after what operation, then you can return everything to its place by performing a system rollback.

There is such a cool feature as system recovery. Below are instructions on how to start it.

1. Open Start and enter your query in the search bar systems recovery.
2. Run the found program.
3. We may be immediately advised to roll back the latest changes.
   
4. But if you know the exact date when the sound disappeared, then it is better to select the option Select a different restore point.
5. In the next step, you need to specify the date on which the computer will be restored. Click Next.
   
6. Specify the drive and click done.
   
7. The computer will reboot and the system changes will be rolled back.
   

And in the saddest cases, when system restore did not help or was completely disabled, then help can help you reinstalling Windows. This seems to me to be the latest attempt to restore sound on the computer

Nothing helped

I hope you've worked through all 10 steps thoroughly before you get to this point.

But if you have done all this, and nothing helps you, then all that remains is to take the computer to a specialist and let him take a look at you. Most likely your sound card is broken and will need to be replaced.

In any case, I ask you to write in the comments how you managed to solve the sound problem on your computer. Wish you luck.

There are different reasons for the lack of sound on a laptop. Sometimes they are quite simple, but in other cases it takes a long time to find the fault. In any case, before you start troubleshooting, you will need to understand what exactly needs to be fixed.

Reasons for no sound

Often the reason for the lack of sound on a laptop is the user's actions. For example, you downloaded new drivers or tried to update existing ones, but due to inexperience or some other reason, you did something incorrectly, after which the sound disappeared.
