This article was written specifically to help users solve any problems related to sound. After all, if there is no sound on the computer, then there can be quite a lot of options for the problem, and searching throughout the network for your specific case is very time-consuming and inconvenient. In addition, the Internet is full of articles that are outdated in their content, which discuss ways to fix them in the operating systems Windows XP, Vista, or at best Windows 7. Now I will tell you what to do if the sound does not work in Windows 10. There are several reasons why there is no sound in the system, and we will look at them all.
The most common case, which is mostly solved in half a minute. It's no secret that for the device to work, it needs to be connected correctly. If the speakers or headphones do not work, check where the wire responsible for the sound is inserted. Typically, the system unit has two or three outputs responsible for sound. They are called linear and look like this:
The output we need is green. As a rule, one is placed in front of the system unit, specifically for connecting headphones, and the other is behind. If you see several audio outputs on the back panel of the system unit, try checking them all. It’s just that one of them is connected to the motherboard, and the other belongs to the sound card. Insert headphones into all outputs one by one and listen for sound.
From the speakers there is a cable, at the end of which there is a plug, usually framed with green plastic or rubber. It is this that needs to be inserted into the linear output, also marked green. And yes, check if the speakers are plugged in and if the power indicator on them is on. Sometimes something as small as unplugged speakers can make people think their computer is irreparably broken.
Advice: “Always carefully read the instructions for the equipment, this will help to avoid many problems.”
A common situation is when you accidentally turn off the sound on your computer while doing some work. To turn it on, you need to resort to the volume control located in the lower right corner of the monitor, which is a drawn loudspeaker. Rice. 0. You need to click on it with the mouse. If you see a picture like this,
then the MUTE key was used (complete instantaneous shutdown).
Or do you see something like this:
here the sound is reduced to a minimum and also does not work. Using the mouse, turn on the sound and set it to the desired level. If the volume control is fine, something may be wrong in the speaker settings. Click the Start button in the lower left corner, then find Settings.
Here are all the settings of our computer, including sound. Type “Sound” in the text field and you will see the complete sound settings of your computer in the drop-down list. Press Enter.
Find “Manage audio devices” in the list and left-click.
A window with audio device settings will open.
Make sure your device is on the list and has a green check mark. This means that it is running and functioning properly. Next, go to its properties.
Take a close look at all volume controls. They should be set to maximum and there should be no crosses anywhere, like in the picture.
Advice: “If you don’t know what will happen when you click on an icon, then it’s better not to click.”
This is a more complicated case, but also quite solvable. First, you need to determine that it is the sound card that is broken. Moreover, now we are considering physical damage, not software. That is, the card burned out or failed.
Open the system unit and visually determine where the sound card is located. It is usually inserted towards the bottom of the motherboard and secured with a latch. At the back it has a line output where speakers are connected. Carefully remove the card and clean it from dust if necessary. Look carefully to see if there are any swollen parts or visible damage on the surface.
Try inserting a different sound card (you can borrow one from a friend) or connect the sound cable to the line-out port of the motherboard.
If sound appears, you will have to buy a new card to replace the burned one, or use the built-in sound card. Remember that sometimes simple cleaning can restore the device.
Advice: “Always keep the inside of the system unit clean and it will work much faster.”
In order for any computer device to work, it needs a special program. It's called "driver". Whether it's a mouse, keyboard, or anything else, they all need to have the correct drivers or they simply won't function. Let's check if you have the correct driver installed on your sound card. Go to Settings, then type Device Manager in the search bar.
Click on it. We are interested in the item “Sound, gaming and video devices”. It contains everything that is installed on your system.
As you can see, opposite the two devices there is a black arrow in a circle. This means that the device is not currently in use. And if a yellow triangle or the words “Unknown device” is shown there, then you need to install the driver.
Right-click on it and click Properties. A window with device properties will open. This is where you can update, remove or roll back the driver.
First, click on “Enable”, this will turn on the device if it is currently disabled.
If there is no driver (the yellow triangle is lit in the “device manager”), click “Update”. The driver will automatically update; you just need to choose where to look for the driver, on your computer or on the Internet.
“Roll back driver” returns the previous version if any problems arise during installation.
“Delete” is the last resort. The device is completely removed from the system. Then you need to restart the computer and, perhaps, this time the system will correctly detect the sound card and automatically install the necessary driver. In this case, you must be connected to the Internet, since Windows 10 uses its driver database, downloading them from the network. Then you need to check the sound, most likely everything will work.
Advice: “If your sound card came with a disc, install everything you need for the device from it. This the best way make the device work correctly."
Everything that happens on your computer is controlled by Windows services. Sometimes, due to certain software problems, these services begin to work incorrectly, which leads to errors, and in our case, to the fact that there is no sound.
To check that the service we need is running, go to Settings, type Services in the text box, and then click View Local Services.
In the window that opens, find the required “Windows Audio” service.
The word “Running” must be present next to it, otherwise the service is disabled. Use the right mouse button to call context menu and select the “Run” sub-item.
Advice: “Don’t mess around with system settings, this can lead to irreparable consequences.”
If the sound suddenly disappeared when you were not doing anything, or after restarting the computer, then there is a high probability of infection with a virus. Most of them do not affect audio devices, but some create problems that completely block sound from the system. Many antivirus programs do not always find such viruses, and if they do, they remove them so that the sound still does not appear.
To solve this case, I recommend that you install the EMSISOFT Anti-Malware program. Being, in fact, a utility, it does not conflict with any antivirus and instantly removes malicious objects. You can download it from our website; in addition, there is a free 30-day version of the product. After installation, click “scan for threats” and the program will find all viruses in the system and restore its functionality.
If the sound disappears after installing a certain program, simply uninstall it and reboot the system. Typically this should help.
It also happens that system sounds are played, but when playing music and movies, there is complete silence in the speakers. How in in this case restore sound on PC and fix the problem? Since there are a huge variety of sound formats, there is a special thing so that they all work and run on one computer. It's called a "codec". For example:
Each of them is needed to launch and work correctly one of the audio formats.
In order not to go through and install them all, there are special assemblies that include most of the well-known codecs. The most famous assembly is called and it consists of a huge archive of sound codecs that allow you to play any known audio formats.
After installation, everything will turn on automatically and problems with no sound are guaranteed to be corrected.
Tip: “Always keep your codec database up to date.”
That's all. I hope the article was useful to you and the question of how to connect sound on a computer is no longer a problem for you.
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, users do not pay attention to the fact that the sound disappears after they:
In any case, if you encounter a problem where the sound on your computer disappears, do not despair. We will look at the most popular problems and ways to solve them, from the simplest to the most complex. Therefore, if you doubt the reasons, then simply follow the instructions, and you will not only figure out why the sound disappeared, but you will also be able to fix the problem yourself.
If your sound card worked fine before reinstalling Windows, but now it fails, then the problem most likely lies in the drivers. In this case, the volume icon can be displayed quite safely in the tray, and after reinstalling Windows will notify you that it has installed all the drivers. However, this does not mean that the drivers were installed correctly and are suitable for your sound card.
In order to fix this problem, you need to do the following:
This method helps in solving most problems related to the fact that the sound has disappeared.
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. It often happens the other way around: the user connects the headphones himself, forgets about it and decides that he has lost the sound.
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.
The next thing to do is find the volume icon in the tray and right-click on it. A context menu will appear. In it you need to select the line “Playback devices”. 
In the window that opens, check which device is used as an audio output (that is, playback devices, not recording devices). By default this should be your computer speakers. All information will be indicated here necessary information about the sound card on the computer. If you are using an additional audio card (USB), it may currently be used as the default device, so change it to external speakers. 
If the playback device is selected correctly, then select the speakers in the list and go to the “properties” tab. Here's a closer look at each individual tab:
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.
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:
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.
It also happens that a green checkmark is displayed next to the playback devices, notifying that the device is working, but there is still no sound. Connect other headphones or speakers to the computer again. Still no audio signal? So the problem is definitely not in the speakers. We continue to search further. The drivers for the audio card may not have been installed correctly. Therefore, it would be useful to remove them again and install them again. In order to do this, you need to go to the device manager. Therefore, open Start and enter “device manager”. 
Or open the toolbar, go to the “Hardware and Sound” block, and then “Device Manager”. 
The “Device Manager” itself will open. Here you need to remove all sound drivers installed on your computer. To do this, right-click on them and select “delete”. 
After you remove all audio drivers, restart your computer. Immediately after turning on, it should automatically begin searching for missing drivers and installing them. 
Usually, this procedure helps restore sound. You can also solve this problem by performing a system restore.
The next problem is when the user installed Windows 7 on his computer and everything except audio works fine. If you start Device Manager, the following icons will appear next to the drivers. 
This usually means that outdated drivers are installed (you have Windows 7, but the drivers were installed for XP). If you are unable to download other drivers, then to fix the problem, you need to do the following:
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:
The next thing you can check is whether the Windows Audio service is running on your computer. To do this, you need:
For easier searching, sort services by name. Find the line "Windows Audio".
Make sure that 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 problem-finding utility built into Windows.
Many users are quite critical of this function. However, she should not be underestimated. Especially in cases where nothing seems to be helping. To begin diagnostics, you must do the following:
An additional dialog box will open where you can select a specific area to troubleshoot. Since we are now trying to configure the sound, we select the appropriate “sound and equipment” block. 
Then the “playback” item. 
You will see a built-in service for troubleshooting Windows problems. For the utility to start working, you just have to click “next” and wait for its results. 
If Windows manages to find the source of the problem, it will automatically download the missing drivers or return the default settings. All you have to do is restart your computer.
If none of the above actions help, then most likely your audio card or other hardware has failed. You can try to perform a system restore or a complete reinstallation of Windows. Especially if you are sure that nothing could have happened to the computer, and the problem appeared after you installed a new operating system. Don't forget that the audio card is exactly the same part of the computer as RAM or processor. Therefore, it has a limited validity period. Perhaps the fact that you have lost sound indicates that it’s time to change it.

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.
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 also regulated by the Flash player, which also has a volume slider and an icon for completely muting the 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). In the screenshot below, see the hot keys of an 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.
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 the 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 for 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:
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. For more detailed information, read the recommendation on how to install drivers on Windows.
After an unsuccessful driver update, you may notice that the sound on your laptop has disappeared. The reason may be that the new driver is damaged or incompatible. In this case, clicking the “roll back” button (returns the previous driver version) in the audio device properties window will help you. Click “yes” in the message.
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.
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:
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.
Why is there no sound on Windows 7? Perhaps many Windows 7 users have experienced this problem at least once. This article contains the most common causes and ways to solve them.
Why does the sound disappear on a laptop, computer, etc.? In most cases, the reason for this is the user's own errors in handling the operating system.
So, what to do if the sound on your laptop does not work. The first step is to check the availability of the necessary drivers for your sound card. Perhaps they need updating, or you don't have them at all. By the way, driver errors are half the reasons why sound on a laptop disappears. In order to see which devices on your laptop or computer need driver updates, you need to open the device manager, which can be found in the control panel.
The manager window organizes and presents all drivers installed on a laptop, computer, etc. Using it, you can check the availability, functionality or relevance of drivers. If any item is marked with a yellow triangle, you should pay attention to it! Devices responsible for sound playback are located in the “Sound, gaming and video devices” tab.
Perhaps the most banal, but at the same time the most common reason for which the sound disappears is its unconscious turning off in the mixer. A mixer is a system that allows you to adjust the volume of specific applications. You can open the mixer by clicking on the corresponding inscription in the volume control window. After starting the mixer, make sure that all parameters are non-zero.
No less common is another reason why the sound on a laptop or desktop computer disappears. Its essence lies in the system disabling the output devices themselves. This may be due to system errors, device configuration changes, or user intervention. Fixing this problem is very easy! For this:
Another common reason is that the service responsible for playing audio is disabled. To start it again, you need to go to Control Panel - Administration - Services. In the window that opens, find the “Windows Audio” service.
If the service is disabled, double-click on the service to open the settings window, from where you can force the service to start by clicking the “Run” button.
In this window, you should configure one more parameter – the startup type. This parameter is responsible for starting the service when Windows boots. In order not to constantly start the service manually, I advise you to define this parameter as automatic.
What to do if there is no sound on the front panel or no sound at all? The whole problem lies in the question “Why is there no sound?”
In most cases, the front panel requires a Realtek controller to operate. If for some reason you don’t have it, be sure to reinstall it. After launching the manager from the control panel, go to the “Speakers” tab. Next, double-click the folder icon in the upper left corner and check the box next to “Disable front panel slot detection”
If, after completing the operation of displaying information on the front panel, the panel is still missing, it means that the BIOS installed in your laptop or computer is most likely incorrectly configured. The BIOS system is present in any laptop, computer or tablet, and provides operating system API access to hardware, including the front panel. To configure the BIOS for the front panel to work, you need to:
Hi all! Modern computer user (unless of course you office worker) It's hard to imagine without music. The lack of sound on the computer is quite sad, because even I am writing this note with a calm track in the background (otherwise the blog posts would be dull and uninteresting). So, I want to tell you about my experience and answer the question - why is there no sound on the computer?
With the transition to Windows 10 and the advent of HDMI (where is the video and the sound is coming one cable and your video card has an audio chip) There are even more problems... this is especially true if your computer is not the latest, even though it coped with the assigned tasks perfectly on Windows 7.
The first thing to do if there is no sound on the computer is to check the cables and make sure that the speakers (or headphones) included. Quite often, a banal reconnection of the speakers helps - if you have already tried all this and the problem with the sound is not solved, then you can start reading the note.
If you connect the speakers to the computer, but there is no sound... then you will have to go to the device manager and see if everything is fine with the hardware and whether we have sound drivers installed. Getting into Device Manager is not difficult - open the Start menu, type “Device Manager” and press Enter on your keyboard.
Device Manager will open. Expand the "Sound, Game and Video Devices" tab. Find in the list (if there are several) your audio device and double-click on it - its properties will open. Check the system message, the driver should be installed and the device should work properly.
Try updating the driver - this is done on the "Driver" tab. Quite often, simply reinstalling the device helps... to do this, right-click on your audio device and click remove (but do not delete the driver itself - the system will ask you about it). After that, click the “Update hardware configuration” button at the top. This will reinstall the existing device driver.
Don't be surprised if you find yourself with multiple audio devices - this is normal. Almost everything modern computer s or laptops have an HDMI video output that can transmit audio and video over one cable
Open "Control Panel" and open the "Hardware and Sound" category. Select Sound. (why can’t you click on the icon next to the clock? - It’s simple, in Windows 10 Spring Creator Updates the interface has changed a little and I’ll describe it below)
Here we are interested in the “Playback” tab and the list of devices. Let's look at an example - I have a laptop connected to an external monitor via HDMI. The monitor has its own built-in speakers... so you just need to tell Windows which device to use for audio playback.
In the example below, as indicated by the green flag, we see that the sound is being played through the monitor (only the speakers on the monitor are turned down to zero! That’s why there is no sound on the computer). You just need to choose standard speakers and sound problems will disappear
It is possible that after selecting a different default audio device, you will need to restart the programs, or better yet, restart your computer for the new settings to take effect.
Windows 10 v1803 continues to nag design of Windows 10 in a new style and in new version These changes affected the sound parameters. In general, there is nothing complicated - right-click on the “Speakers” icon next to the clock and select “Open sound options”
Everything is similar here, we just select an output (playback) device from the list and enjoy the sound on the computer.
Several audio devices will be active if you connect the TV to a laptop or computer via HDMI... perhaps you are using Bluetooth speakers and much, much more...
In Control Panel (in the same place where you selected the default audio devices on the “Playback” tab) Right-click on “Default Playback Device” and open its “Properties”. In the Enhancements tab, select "Disable all audio enhancements" and check if the sound is working.
If these manipulations helped, this is good news, turn off sound effects for all your audio devices.
Almost all modern computers are equipped with at least three connectors, which necessarily include:
(exceptions are laptops; quite often they are combined and have only one dual-use connector - microphone and line output). Make sure your speakers are connected to line out (usually it is colored green).
Maybe the advice is so-so, but you can try connecting to all connectors to determine at random the one you need
I would like to draw your attention to the fact that when you connect headphones to the front panel of the system unit, the speakers will turn off - do not forget this nuance.
This problem probably deserves a separate note, but I’ll try to tell it in the context of our problem. If you connected your TV via HDMI and are faced with no sound on it, you need to delve a little deeper into history.
If your computer and TV are completely new, then most likely your default playback device is incorrectly selected; you can read above how to change it.
If your computer is no longer young, then it is quite possible that although there is an HDMI connector on your video card, it cannot transmit sound via this cable. In this case, either change the video card or connect the sound to the TV with a separate cable (if possible).
In Control Panel, open the properties of your default playback device and go to the Advanced tab. In the Default Format section, check each available one in turn.
If it helps, save the settings and enjoy the sound on your computer. However, as practice has shown, this method It helps very rarely.
If you are already desperate and have tried everything possible options, then starting with Windows 8 there is an opportunity to automatically try to fix the problem with no sound on the computer. Click on the speaker icon in the taskbar and select “Troubleshoot sound problems”
Next, you need to select your playback device and follow the prompts... if you look closely at the points, you can see that the system itself tries all the methods described above and, if possible, combines them. Surprisingly, quite often this method helps, especially in cases where you have chosen the wrong device for sound output in the system.
Well friends, in this guide I described the most common problems with no sound on a computer. In fact, there are many more reasons why there is no sound on a computer or laptop, but it is better to consider them privately. If these methods did not help you in any way, then please describe your problem in as much detail as possible in the comments - I will definitely answer and try to help you.
