with the keyboard or mouse.

CD to record, increases the CD level by ten (both left and right),
and prints the new settings for the microphone.
The .aumixrc file containing:
sets the volume to 60%, waits five seconds, then reduces the volume to 50%.
Note that "wait" lines will not be saved by aumix. They must be added by hand.
If no options are given on the command line, and
is compiled with ncurses, it will run interactively.
The left bank of controls is used for adjusting levels; the right
bank is for adjusting balance.
Mixing channels not supported by your hardware will not be shown.
Mixing channels which are stereo-capable will have balance controls.

Saved settings for the mixer are kept in the
files, but can be kept anywhere if specified explicitly.
Color schemes are normally kept in the directory given
at compilation time, but are preferentially loaded
from the current directory and can be kept anywhere so long as the
path to them is specified.

The words should be separated by whitespace and can be upper-,
lower-, or mixed-case.
Lines not matching all these conditions are ignored.
Some samples of color schemes are provided, named
after the sort of terminal where they should be most suitable.
If either foreground or background is given as

The defaults are a white foreground and black background.
An xpm icon is provided.
