Mute Windows sound when activating screen lock

Windows 10 has a screen lock feature. When we use it, we can prevent other users from using our PC when we are not in front of us. However, when the system enters screen lock mode, it does not prevent or disable the applications that we are running. This means that, if we are listening to music with our player, the system will lock when it does not detect activity such as the use of the keyboard or mouse, but it will not deactivate said application, so it will continue to sound even when it is locked.

And it is that Windows, by default, does not have any function that allows us to turn off the sound once the lock screen or screensaver has been activated, something that could be useful in certain circumstances when we are not in front of the screen. In this way, if we want to have this possibility, it will be necessary to use applications developed by third parties, especially indicated to help us with this work and that we can use completely free of charge.

Mute audio automatically with WinMute

If we want to silence Windows automatically when it is blocked, we can use an application like WinMute, which we can download for free from the following link. This program is compatible with all kinds of web browsers and multimedia players, allowing us to control the volume from the system so that it is possible mute the audio. The software runs in the background and is housed in the system tray, so it does not have a graphical interface. We can open its configuration menu by clicking on its icon with the right button.

While the program is running, all system audio will be muted automatically every time Windows hangs or skips the screen saver. From its panel we have the option to silence the computer when it is locked, when the screensaver comes out and the possibility of restoring the volume when it has been activated again.
