pamixer: pulseaudio command line mixer

pamixer is like amixer but for pulseaudio. It can control the volume levels of the sinks.

Also, this project can provide you a small C++ library to control pulseaudio.


  • Get the current volume of the default sink, the default source or a selected one by his id
  • Set the volume for the default sink, the default source or any other device
  • List the sinks
  • List the sources
  • Increase / Decrease the volume for a device (using gamma correction optionally)
  • Mute or unmute a device


  • libpulse
  • boost-program_options

You need the headers as well (“-dev” packages for Debian).


  • From source:

    • Get the source:

      git clone
    • Compile:

    • And use it, no install command for now:

      ./pamixer --help
      Allowed options:
        -h [ --help ]         help message
        --sink arg            choose a different sink than the default
        --source arg          choose a different source than the default
        --default-source      select the default source
        --get-volume          get the current volume
        --get-volume-human    get the current volume percentage or the string "muted"
        --set-volume arg      set the volume
        -i [ --increase ] arg increase the volume
        -d [ --decrease ] arg decrease the volume
        -t [ --toggle-mute ]  switch between mute and unmute
        -m [ --mute ]         set mute
        --allow-boost         allow volume to go above 100%
        --set-limit arg       set a limit for the volume
        --gamma arg (=1)      increase/decrease using gamma correction e.g. 2.2
        -u [ --unmute ]       unset mute
        --get-mute            display true if the volume is mute, false otherwise
        --list-sinks          list the sinks
        --list-sources        list the sources
