pamixer's Introduction

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
