Audio mixer tool. Run without any options or arguments for an ncurses-based interactive mode.
The first set of options sets the volume level of a channel to a percentage of the maximum. Each channel is represented by a single letter or number: v for overall volume, b for bass, t for treble, s for synthesizer, w for PCM channels, c for CD, m for microphone, i for line in, o for line out, l for the main line, x for imix, and 1, 2, or 3 for lines 1, 2, and 3. Passing q as an argument to any of those flags displays their current status. Passing + or - will increase or decrease the channel volume by one, and +n or -n will adjust them by n.
For example, aumix -c q -l 10 will display the CD value and set the main line to 10%.
