pamixer

A simple command-line mixer for PulseAudio. More information: https://github.com/cdemoulins/pamixer#installation.

• List all sinks and sources with their corresponding IDs:

pamixer --list-sinks --list-sources

• Set the volume to 75% on the default sink:

pamixer --set-volume {{75}}

• Toggle mute on a sink other than the default:

pamixer --toggle-mute --sink {{ID}}

• Increase the volume on default sink by 5%:

pamixer {{[-i|--increase]}} {{5}}

• Decrease the volume on a source by 5%:

pamixer {{[-d|--decrease]}} {{5}} --source {{ID}}

• Use the allow boost option to increase, decrease, or set the volume above 100%:

pamixer --set-volume {{105}} --allow-boost

• Mute the default sink (use --unmute instead to unmute):

pamixer {{[-m|--mute]}}
