This program adjusts the settings of an audio mixing device. It can be used from
the command line, in scripts, or interactively with the keyboard or mouse.

aumix interactively, using the full-screen
ncurses-based interface. This is the default if no options are given, but
must be specified in order to have
aumix go into
interactive mode after doing things non-interactively.
- load settings from $HOME/.aumixrc, or
/etc/aumixrc if the former is inaccessible
- query all devices and print their settings
- save settings to $HOME/.aumixrc
aumix -q -v75 -m 0 -c R -c+10 -m q
prints all settings, sets volume to 75%, sets microphone to 0,
sets 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.
The following keys control
aumix in interactive mode:
- page up, page down, up and down cursor
- select a new control.
- Tab, Enter, <, >, comma and period
- toggle between level and balance controls
- +, -, [, ], left and right cursor and digits
- adjust the setting of the current device. The
and right cursor keys increase the level by 3%; the
- and left cursor keys decrease it by the same
[ key sets it to 0% and
0 set it to 100%. The
9 set it to
10% through 90%. The same keys work analogously on the balance

Saved settings for the mixer are kept in the
$HOME/.aumixrc files, but can be kept anywhere if
specified explicitly. Color schemes are normally kept in the directory given
DATADIR 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 format of these files is:

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

Suspending with ^Z may make the terminal difficult to use.
