man mute (Commandes) - use aumix to mute your soundcard
NAME
mute - use aumix to mute your soundcard
DESCRIPTION
mute is a small script that uses aumix to allow you to conveniently mute and unmute your sound.
If your sound is currently not muted, running mute will save your current settings to ~/.aumixrc (or /etc/aumixrc if you are root) and mute the sound. Running mute again will restore the settings.
mute does not take any command line arguments.
BUGS
Your current ~/.aumixrc will be overwritten.
