aumix -- adjust audio mixer
aumix [-<channel option>[[+|-][<amount>]]|<level>|R[ecord]|P[lay]|q[uery]] [-dhILqS] [-f <rc
file>][-C <color scheme file>]
This program adjusts the settings of an audio mixing device. It can be used from the com-
mand line, in scripts, or interactively with the keyboard or mouse.
-v main volume
-i line in
-o line out
-p PC speaker
-1 line 1
-2 line 2
-3 line 3
For each channel, q queries, + and - increment and decrement by one, or an amount if one is
specified. If no + or - is given after the channel option, a number sets a specific level
specify the name of a file containing a color scheme. This implies -I.
specify the name of the mixer device (default is /dev/mixer)
-f rc_file specify file for saving and loading settings
-h display information on usage
-I run 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.
-L load settings from $HOME/.aumixrc, or /etc/aumixrc if the former is inaccessible
-q query all devices and print their settings
-S 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 aumix is compiled with ncurses, it will run
The left bank of controls is used for adjusting levels; the right bank is for adjusting bal-
ance. 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 amount. The
[ key sets it to 0% and ] sets it to 100%. The digits 1 to 9 set it to 10%
through 90%. The same keys work analogously on the balance controls.
Space toggles between record and play for controls which are capable of this.
| centers the balance of the current device.
K or k show a description of the functions of keys
L or l load settings from $HOME/.aumixrc, falling back to /etc/aumixrc
M or m mute or unmute
O or o ``only'': mute all channels but the current one
S or s save settings to the rc file
U or u undo any muting
Q or q end the program
^L refresh screen
^Z, ^D and ^C also have their normal function (the screen is refreshed when aumix is brought
to the foreground).
In interactive mode, aumix can accept input from the mouse if gpm(8) is running and aumix is
compiled with gpm(8) support. If gpm is not running but gpm support is included, the mes-
sage 'mouse off' will appear at the top of the screen, and only keyboard input will be
accepted. With gpm(8) running, most functions can be performed through the mouse. The
mouse is active whenever one of its buttons is held down. While active, it works in the
o over a control track, it sets the control to match the position of the mouse cursor.
o over a record/play indicator, it toggles the record/play state.
o over the 'Quit', 'Load', 'Save', 'Keys', 'Mute', 'Only', or 'Undo' labels at the top of
the screen, it causes those actions to take place.
The HOME variable is used. When aumix is compiled with GTK+ support, DISPLAY is checked,
and if set is used. LANG is used when aumix the ncurses screen is displayed.
Saved settings for the mixer are kept in the /etc/aumixrc and $HOME/.aumixrc files, but can
be kept anywhere if specified explicitly. Color schemes are normally kept in the directory
given by DATADIR at compilation time, but are preferentially loaded from the current direc-
tory and can be kept anywhere so long as the path to them is specified. The format of these
item foreground background
where item is one of 'active', 'axis', 'handle', 'menu', 'play', 'record', or 'track' and
foreground and background are one of 'black', 'red', 'green', 'yellow', 'blue', 'magenta',
'cyan', or 'white'. 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 '-', then the default color for that is used.
The defaults are a white foreground and black background.
An xpm icon is provided.
This page corresponds to version 2.7.
Suspending with ^Z may make the terminal difficult to use.

Information such as the version of aumix, the architecture and operating system, and the
model of sound hardware is sometimes needed to diagnose problems, so it is best if you
include such details in any bug reports.
