Linux utility for controlling alsa output and notifying the user of changes. Useful for those who use minimal Window Managers (e.g. XMonad, Awesome, i3) instead of full-blown Desktop Environments (e.g. GNOME, KDE, XFCE), but still want to use multimedia keys to control the volume.
The whole implementation is based on the following behavior:
- The "Volume Up" key should increment the current (master) volume by a fixed amount
- The "Volume Down" key should decrement the current (master) volume by a fixed amount
- Only one of the outputs should be active at a time, therefore the "Mute" key rotates between the outputs (plus a mute state)
The implementation consists of two parts: a daemon, which listens on D-Bus for
commands, and a corresponding command-line client. For more information on how
to use those programs, call them on the command line with option --help.
The recommended usage is then to bind your multimedia keys to the appropriate commands,
e.g. the "Mute" key to soundctl cycle_outputs.
The only supported OS is currently Linux. Users should have ALSA and D-Bus installed. This is not compatible with PulseAudio.
The following python libraries are used:
- PyAlsaAudio/
- dbus-python version 1.0.*
