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.

Features

• 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

Dependencies

• libpulse
• cxxopts

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

Installation

• From source:

  • Get the source:

    git clone https://github.com/cdemoulins/pamixer.git

  • Compile:

    meson setup build
    meson compile -C build

  • And use it:

    ./build/pamixer --help
    pulseaudio command line mixer
    Usage:
      pamixer [OPTION...]
    
      -h, --help              help message
      -v, --version           print version info
          --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         increase/decrease using gamma correction e.g. 2.2
                              (default: 1.0)
      -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
          --get-default-sink  print the default sink

  • Or install it:

    meson install -C build
