How to Mute or Unmute Sound on Ubuntu Linux
You can mute or unmute sound on Ubuntu Linux by using quick controls in the system menu or more detailed options in the Settings app.
Muting your computer entirely stops all audio output, while unmuting restores it. This is distinct from simply lowering the volume, which reduces the sound level without eliminating it.
For example, on Ubuntu 22.04 LTS, you access the primary mute toggle by clicking the system status area in the top-right corner of your screen. This area displays icons for Wi-Fi, battery, and system settings.
Quickly muting your system is useful for preventing unexpected noise during calls or when you need immediate quiet.
Mute or unmute sound on Ubuntu by clicking the system menu in the top-right corner and using the volume slider. Slide it all the way left to mute, or move it right to unmute and adjust volume.
