How to restore sound on a Windows 7 laptop. How to restore sound on any laptop using different methods? Enable the audio service

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

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

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

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

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

Checking the correct connection and functionality of the speakers

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

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

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

Windows Settings

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

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

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

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

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

Playback devices are empty

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

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

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

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

Playback devices are on but there is no sound

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

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

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

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

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

There are strange symbols in the device manager

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

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

Turn on sound in BIOS

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


Checking the health of services

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

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

For more convenient search, sort services by name. Find the line "Windows Audio".

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

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

Windows Diagnostics

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


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

Then the “playback” item.

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

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

Audio card malfunction

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

The cause of the malfunction can only lie in two places: in the hardware of your computer, or in its software. In other words, the absence of sound is a consequence of a malfunction in the "hardware" PC, or is it related to the operating system settings, incorrect work some programs. It should be understood that the occurrence of such a breakdown does not depend on the OS or its newness. This happens both in older versions, such as Windows XP, and in the most latest Windows 8. This can also happen on Linux and other operating systems. Even if your equipment is the newest and most modern, the most expensive sound card, the highest quality speakers, you can still encounter a similar problem.

How to restore sound on a computer?

First, we must find out the very cause of the problem. We will determine the reason for the lack of sound in various ways, let's start with the simplest and most basic ones.

To do this, we will follow, step by step, according to the following instructions:

If none of the above points helped you, then you need to use the latest option - call a technician for help, or take the PC to a workshop.

If the sound does not play or becomes bad.

In such cases, first of all, it is necessary to remember what actions were performed on the computer in last time when the sound was normal. Perhaps you installed something new. In this case, the problem can be solved quite easily by uninstalling the program that you installed. In other cases, the problem may be due to the accidental removal of some important component in the operating system. Therefore, you should be careful about all programs that you delete. Follow all the recommendations for troubleshooting that were described above, most likely something will help. Always, in any unclear situations, you can use the help section, which is located in the menu Start.
When the sound is hoarse or otherwise distorted, check your audio settings. It may have gone wrong, or you may have accidentally added some sound effect that is now playing along with the sound.

It happens that the sound generally works fine, but in some one specific program, is reproduced (or not reproduced) of poor quality. This can be solved by examining the sound settings in the program itself, or, as a last resort, reinstalling it, this should help.

Troubleshooting sound problems in Windows 7 and Windows XP

This add-on will discuss step by step what to do when the sound on the computer in operating rooms is lost Windows systems XP and Windows7. So let's start in order:

Look in the bottom right corner of the screen for the location of the clock, which is displayed in the form of a speaker.

If this icon is missing, as in Windows XP, check the settings through the control panel located in the “Sounds and Audio Devices” section (instructions for Windows XP, point 4).

By left-clicking on this icon, you should make sure that the sound is on and the volume control is not located at the very bottom.

A window will open in which you need to mark whether the controls are enabled:

  • Volume in mixer Windows7, Vista;

  • Volume in the Windows XP mixer.

If you cannot change the settings due to the parameters being deactivated (they are highlighted in pale gray), the health of the audio device is checked in the task manager (step 3). If there are problems, you will need to reinstall the audio driver (step 6).

Before checking the settings and status of your sound card, make sure your speakers or headphones are turned on or connected correctly. The audio card contains a pin for connecting audio speakers, marked in green.

When installing more than one on your computer sound card, you need to ensure that the speakers are connected to the connector of the working card (which is used by the system). The wire connecting the speakers to system unit, should fit snugly.

It is best to check the performance of the speakers on another computer, or by connecting one of the suitable devices to the audio output.

To enter the “Device Manager”, click sequentially:
On Windows7 or Vista:

“Start”, then “Settings”, then “Control Panel” and “Device Manager”.

On Windows XP:

Right-click to open the context menu by clicking on the “My Computer” icon, selecting “Properties”, going to the “Hardware” tab and clicking “Device Manager”.

Your audio device should appear under Sound, video and gaming devices.

If there is no device or location exclamation mark On the contrary, the issue is a damaged or missing driver. In this case, the driver is completely updated or reinstalled (point 6).

To open the audio settings window in Windows 7 and Vista, you will need to click “Start”, then “Settings”, “Control Panel” and “Sound”.

After this, a dialog box will open in which a list of all your devices will be visible. In this case, the default is one device:

The fact that the audio is working correctly is indicated by the corresponding inscription under the name with a green checkmark near the device icon.

If this window shows a different picture, characterizing obvious interruptions in the operation of the device, you will need to reinstall the driver (step 6).

On Windows XP:

Next, go to the “Volume” tab and make sure that the “Mute sound” checkbox is not checked. The mixer volume must be above zero.

If at this stage the settings are normal, but the sound on the computer disappears and does not return, proceed to the next step.

If it is impossible to move the mixer volume control and the presence of the inscription: “There are no sound devices” instead of your device, this serves as a signal that you need to reinstall the sound driver, or that the sound card is faulty (point 6).

To do this, open: “Start”, then “Settings”, then “Control Panel”, click “Administration” and at the end - “Services”. But a slightly different option is also possible.

“Start” – “Run”, then enter the command services.msc in the line, clicking “OK” to complete. A window will open in which you will need to find a service called “Windows Audio”.

If the service is started and running in “Auto” mode, as is clearly demonstrated in the figure, you will need to close the window and move on to the next step.

If the service is disabled, you will need to enable it. After selecting it with the right mouse button, click “Properties” in the drop-down menu.

In the properties window, you need to do the following:

  1. Set the startup type to “Auto”;
  2. Click “Run” (in Windows 7 or Vista), or “Start” (for Windows XP);
  3. Click “Apply” and then “OK”.

If there is no effect, you can proceed to subsequent actions.

If problems are detected in the device manager, or in the window with audio parameters settings, indicating that the sound device is not working correctly, we are talking about a damaged or incorrectly working sound driver. You will definitely need to update it or reinstall it.

You can find the sound card driver on the disk that comes included, or on the disk with drivers for the motherboard with a sound device integrated into the system board. A disk with drivers for the motherboard is provided with the computer at the time of purchase. Drivers must be suitable for your operating system (OS). For example, if you have Windows 7 and a disk with drivers for Windows XP, just download it from the card (motherboard) manufacturer’s website required driver.

Let's say there is a suitable package for installation necessary drivers you have. In the “Device Manager” (“Control Panel”, “System”, “Hardware” and “Device Manager”), the currently installed audio driver will need to be removed. If the above is missing, you need to find “Multimedia audio controller”, and then remove the audio-video codecs installed on your PC. To do this, you will need to call “Add or Remove Programs” from the Control Panel, and then click on restart the system.

Restarting your computer in Windows 7 will allow you to update the system automatically using technology Plug and Play. To install manually, you will need to insert the driver disc into the drive.

Let's try to look at installing drivers, focusing on Windows XP. Differences in Windows versions are only minor differences appearance dialog boxes.

Once you open the Device Manager window, look for the section that has “sound” or “multimedia” in its name. To open the device properties, simply double-click on it. Having selected the “Driver” tab, you need to click the “Update” button. A menu will open in which the system will prompt you to automatically or manual installation. Click the second item and then the “Next” button:

After the window opens, check the “Include next search location” checkbox next to the item. The Browse button will help you specify the optical drive with the disc. By clicking the “Next” button, find the necessary drivers and install them.

Upon completion, you will receive a system notification that the driver installation was successful and you can use the equipment. As a result, you will be pleased with the sound that appears. In extreme cases, this will happen after a reboot.

7. Check if the settings in BIOS are correct

There may also be no sound in Windows due to the integrated audio card being turned off in the BIOS settings. To start the computer, press the Del button. In some PC models these are the F2, F10, F12 keys. In the list of motherboard devices, you will need to find the sound card, and then make sure that the switch opposite is set to the “Enabled” position.

A common reason for sudden loss of sound on a computer is a broken sound card. However, before purchasing a new one, you should make sure that after applying the above options, no actions help.

The main thing to remember is that any problem can be solved and the solution may turn out to be much simpler than it seems.

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

Reasons for sound loss

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

  1. software;
  2. mechanical.

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

To the main software reasons can be attributed:

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

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

Photo: checking standard settings

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

The following mechanical faults can be mentioned:


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

Volume muted

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

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

Video: no sound on Windows 7

The service responsible for sound is disabled

This is not an uncommon accidental error.

To check audio services:


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

There is another way to access the configuration settings, this requires:


Driver corruption

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

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


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

Briefly it can be written like this:


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

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

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

Sound card problems

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

If this action does not resolve the problem, and the status line of the controller indicates that it is working with errors, you should contact the service center. Most laptops have an integrated motherboard sound module, which can be repaired regular user I can't.

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

Fixing sound with Microsoft Fixit Audio

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

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

After verification, you will be notified if:

  1. its launched Windows services, which are responsible for sound;
  2. sound devices are disabled;
  3. volume set to low;
  4. the installed device is not the default playback device;
  5. the module is not connected;
  6. problems with HDMI ports;

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

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

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

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

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

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 on a Windows 8 laptop? And why will it be both easier and more difficult to deal with the problem in this operating system?

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;
  • Finite Builder Windows points Audio;
  • 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.

  1. 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 drivers are 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;
  2. Sometimes drivers just need to be updated. Again, either all or only some;
  3. 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 audio 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 (it’s better to make sure of this at this point).

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, a more specific case when Fn sound does not work on Windows 8. Unfortunately, this happens everywhere.

Sometimes drivers for this operating system have not yet been released for the required laptop model, 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;
  • operating systems;
  • 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.

Hello.

I never thought that there could be so many problems with sound! It is undeniable, but it is a fact - a fairly large number of laptop users are faced with the fact that at one point the sound on their device disappears...

This can happen for various reasons and, most often, you can fix the problem yourself by delving into Windows settings and drivers (thanks to which you can save on services computer services). In this article I have collected some of the most common reasons, due to which the sound disappears on laptops (which even a novice PC user can check and fix!). So…

Reason #1: Adjusting the volume in Windows

I, of course, understand that many may express dissatisfaction - “ that this is really..." for such an article. But still, many users do not know that the sound in Windows is controlled not only by the slider, which is located next to the clock (see Fig. 1).

Rice. 1. Windows 10: volume.

If you click on the sound icon (located next to the clock, see Fig. 1) with the right mouse button, several additional options(see Fig. 2).

  1. volume mixer: it allows you to set your own volume in each application (for example, if you don’t need sound in the browser, then you can turn it off there);
  2. playback devices: in this tab you can choose which speakers or speakers to play sound through (and in general, this tab shows all the sound devices connected to the device. Moreover, sometimes even those that you don’t have! Can you imagine, sound can be supplied to non-existent devices ...).

IN volume mixer Pay attention to whether the volume in your running application is turned down to a minimum. It is recommended to raise all sliders up, at least while troubleshooting and troubleshooting audio problems (see Figure 3).

In the " Playback devices» please note that you have there may be several devices(I have only one device in Fig. 4) - and if the sound is “sent” to the wrong device, this may be the reason for the loss of sound. I recommend that you check all the devices displayed in this tab!

Rice. 4. Sound/playback tab.

By the way, sometimes the built-in Windows wizard helps you figure out and find the causes of sound problems. To launch it, just right-click on the sound icon in Windows (next to the clock) and launch the corresponding wizard (as in Fig. 5).

Rice. 5. Troubleshoot audio problems

Reason #2: drivers and their settings

One of the most common causes of problems with sound (and not only with it) is conflicting drivers (or the lack thereof). To check their availability, I recommend opening device Manager: To do this, log in panel Windows management , then switch the display to large icons and launch this manager (see Fig. 6).

Next, open the “ Sound, gaming and video devices". Pay attention to all lines: there should be no yellow exclamation marks or red crosses (which mean there are problems with the drivers).

By the way, I also recommend checking the drivers in the utility Driver Booster(there are both free and paid version, differ in operating speed). The utility quickly and easily helps you check and find the necessary drivers (an example is shown in the screenshot below). What’s convenient is that you don’t need to independently search on various software sites, the utility itself will compare the dates and find the required driver, all you have to do is click a button and agree to install it.

Article about programs for updating drivers: (including Driver Booster)

Reason #3: the sound manager is not configured

In addition to the sound settings in Windows itself, the system (almost always) has a sound manager, which is installed along with the drivers ( in most cases this is Realtek High Definition Audio). And quite often, it is in it that questions may not be specified optimal settings, which make the sound inaudible...

How to find it?

It's very simple: go to Windows control panel, and then go to the “ Equipment and sound". Next on this tab you should see the manager that is installed on your equipment. For example, on the laptop that I am currently setting up, the Dell Audio application is installed. This software needs to be opened (see Fig. 10).

Another important point: You need to check whether the laptop correctly detects the device connected to it. For example, you inserted headphones, but the laptop did not recognize them and does not work with them correctly. Result: no sound in the headphones!

To prevent this from happening, when you connect the same headphones (for example), the laptop usually asks if it has identified them correctly. Your task: to show him the right sound device(which you connected). Actually, this is what happens in Fig. 12.

Reason #4: The sound card is disabled in the BIOS

On some laptops, you can disable the sound card in the BIOS settings. This way you are unlikely to hear sound from your mobile “friend”. Sometimes BIOS settings can be “accidentally” changed by inept actions (for example, when Windows installation Not experienced users often they change not only what is needed...).

Actions in order:

2. Since BIOS settings vary depending on the manufacturer, it is quite difficult to give universal instructions. I recommend going to all the tabs and checking all the items that contain the word “Audio“. For example, Asus laptops have an Advanced tab, in which you need to switch the High Definition Audio line to Enabled mode (i.e., turned on) (see Fig. 13).

Reason #5: lack of some audio and video codecs

Quite often the problem occurs when trying to play a movie or audio recording. If there is no sound when opening video files or music (but there is sound in other applications), the problem is 99.9% related to the codecs!

  • first remove all old codecs from the system completely;
  • then restart the laptop;
  • reinstall one of the sets proposed below (you can find it at the link) in full advanced mode (this way, you will have all the most necessary codecs in your system).

For those who do not want to install new codecs on the system, there is another option: download and install a video player, which already contains everything you need to play the most popular files. various types. Such players are becoming quite popular, especially recently (and no wonder, who wants to suffer with codecs?!). You will find a link to an article about such players below...

Reason #6: sound card problem

The last thing I wanted to dwell on in this article is the problems of the sound card (it can fail during sudden surges in electricity (for example, during lightning or welding)).

If this happened, then in my opinion, the most best option- use an external sound card. Such cards are now available at a price ( especially if you buy it in some Chinese store... At least it’s much cheaper than looking for a “native” one) and represent compact device, slightly larger than a regular flash drive. One of these external sound cards shown in Fig. 14. By the way, such a card often provides much better sound than the built-in card in your laptop!
