First, sound is a component Essential of a computer. Similarly, of course you can use a computer without sound, but reduce what you can do with it. So, most entertainment options disappear if you have no sound. Also, if you trust sound or audio alerts, they cannot be played. If you suddenly notice that there is no sound in your system's speakers, here we will help you.
Reboot your system
First, this tip will never go out of style, so try to turn off the system and turn it on again to see if the sound returns. There may be a problem starting your system and the sound driver did not load correctly. Now, if you have an application installed to improve the sound, you better remove it. If this pair of basic tricks doesn't work for you, then here are more options.
Repair the speakers: run the sound troubleshooter
First, you must open the Settings application. And then, you must go to the "Update and security" configuration group. You must select the "Troubleshoot" tab. Now, scroll down and run the troubleshooter; For audio problems. You must apply all the corrections they recommend. Now, restart your PC.
Check the enabled device
For this option, you must access the sound settings of the Control Panel. You must go to the "Playback" tab. And right click on an empty area within the list of enabled devices. In the context menu, select “Show disabled devices” and also in: “Show disconnected devices”.
Now, check if new devices appear. If your speakers appear, right-click on them and select the enable option in the context menu. The speakers may be disconnected, which you should deal with in Device Manager.
Repair the speakers: Install or connect the device
Also, disconnected speakers can be a hardware or software problem. Before deciding to inspect the hardware, you have to rule out all problems with the software. To do this, open Device Manager and expand "Sound, videos and juice controllers." Find your sound card. Then, right-click and select "Properties" in the context menu.
Similarly, in the "Properties" window, you must go to the "Controller" name tab. Check if there is a button to enable the device. If there is, click on it and then restart your operating system.
Repair speakers: sound drivers
If the sound disappears from your system, it may have something to do with the drivers. You will have to try several different things, but you will work primarily only with Device Manager. You must expand the sound, video and game controllers and go to the properties of your sound card. Now, you must go to the "Driver" tab and look for driver updates.
Similarly, install the available updates, restart your system and check the sound. If this does not work, go back to the Controller tab and click on the option “exit to previous controller”; If there is the option there. Now, restart Windows 10 and verify the sound.
Now, try a different driver. You can use Realtek controllers or generic Micrososft sound controllers. To change the drivers you are using, choose to update the driver. But instead of letting Windows 10 verify the available updates, choose the "Choose drivers from a list" option.
Finally, try to manually install the sound drivers. Find the latest version of the sound drivers available for your system and install them from outside the Device Manager.
Windows updates
Now, check if your Windows 10 recently received an update. It could be a feature update or a smaller update. That could have caused some problems. Go back to the update and check if this solves the problem. Similarly, you can reverse the update from the “Settings” application in Update and security.
End of hardware life
Now, if your PC is particularly old, your hardware may no longer be compatible. It is possible that a driver update or a Windows 10 update has been installed to make the audio mute. It's weird since the sound is quite simple but it can happen. You will have to go back to previous compatible versions of the driver or operating system. Or, update your system.
Finally, if this has not worked, you may have to consider the idea that something is wrong with your computer hardware.
