SoundSource

This project contains a version of Rogue Amoeba's SoundSource 2.5 with an added command line tool for switching audio devices and setting volume.

If you want a graphical version of SoundSource, you can get one from Rogue Amoeba. Current versions of Rogue Amoeba's SoundSource are commercial products, not open source.

The command line tool has no man page yet, but here's a simple example of how to use it:

% soundsource -h
usage: soundsource [-ios] [device]
   or: soundsource [-IOS] volume
   or: soundsource [-Mm]
  -i         display selected audio input device
  -o         display selected audio output device
  -s         display output device used for alert sounds, sound effects
  -i device  set selected audio input device
  -o device  set selected audio output device
  -s device  set output device used for alert sounds, sound effects
  -I         display selected audio input device's volume
  -O         display selected audio output device's volume
  -S         display alert sounds/sound effects volume
  -I volume  set selected audio input device's volume
  -O volume  set selected audio output device's volume
  -S volume  set alert sounds/sound effects volume
  -M         mute selected audio output device
  -m         unmute selected audio output device
With no arguments, displays available/selected (*) devices and volumes.
