The reason for the computer suddenly losing sound may be due to sound settings, drivers, playback devices or system errors. Below are simple fixes that users can do themselves.
Check the volume on the computer
Sometimes the sound is turned off or reduced to the lowest level.
How to do it: Tap the speaker icon on the Taskbar → Volume check → Uninstall Mute mode if it is on → Increase volume to an appropriate level.
Check the sound emitter
Windows may be choosing the wrong speaker or headset.
How to do it: Press the speaker icon on the Taskbar → Select the correct sound player (Speaker or Headphone) → Play a sound test.
Check for speakers or headphones
If using external speakers or headphones, check the connection.
How to do it: Remove and replug the audio or USB jack → Try plugging it to another port → Reconnect the Bluetooth device if using wireless headphones.
Restart the computer
Some audio errors only occur temporarily after updating or installing the software.

Run a sound fix program
Windows integrates tools to automatically detect and correct sound errors.

If the sound service is stopped, the computer will not make a sound.
