Ubuntu Manpage: aumix — adjust audio mixer

NAME

       aumix — adjust audio mixer

SYNOPSIS

       aumix  [-<channel  option>[[+|-][<amount>]]|<level>|R[ecord]|P[lay]|q[uery]]  [-dhILqS] [-f <rc file>][-C
             <color scheme file>]

DESCRIPTION

       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.

OPTIONS

   CHANNEL OPTIONS
       -v          main volume
       -b          bass
       -c          CD
       -i          input gain
       -l          line
       -m          microphone
       -o          output gain
       -p          PC speaker
       -r          record
       -s          synthesizer
       -t          treble
       -w          PCM
       -W          PCM 2
       -x          mix monitor
       -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 (monophonically).

   OTHER OPTIONS
       -C color_scheme_file
                   specify the name of a file containing a color scheme.  This implies -I.  This option  can  be
                   used  to  force  the  ncurses interface with a GTK version.  No need to specify a filename in
                   that case.

       -d device_file
                   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.
                   To force use of the ncurses interface with the GTK version, specify -C (no  need  to  give  a
                   filename).

       -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

EXAMPLES

       The command

             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:

             vol:60:60
             wait:5000
             vol:50:50

       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.

INTERACTIVE USE

If no options are given on the command line, and aumix is compiled with ncurses, it will run
interactively.

LAYOUT
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.

KEYS
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 ]
or 0 set it to 100%. The digits 1 to 9 set it to 10% through 90%. The digit 0 sets it to
100% (not 0%). 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).

MOUSE
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 message ‘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 following ways:
• over a control track, it sets the control to match the position of the mouse cursor.
• over a record/play indicator, it toggles the record/play state.
• over the ‘Quit’, ‘Load’, ‘Save’, ‘Keys’, ‘Mute’, ‘Only’, or ‘Undo’ labels at the top of the screen,
it causes those actions to take place.

ENVIRONMENT

       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.

FILES

       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 directory and can be  kept  anywhere  so
       long as the path to them is specified.  The format of these files is:

             item foreground background

       where  item  is  one  of  ‘active’,  ‘axis’, ‘handle’, ‘hotkey’, ‘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.  If aumix is
       linked  against  ncurses,  then  the terminal's default fore or background will be used; else the default
       foreground is white and the default background is black.

       An xpm icon is provided.

VERSION

       This page corresponds to version 2.9.1.

BUGS

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