10 __DESCRIPTION__

13 This program adjusts the settings of an audio mixing device.
14 It can be used from the command line, in scripts, or inter-
15 actively with the keyboard or mouse.

This implies -I. This option can beused to force the ncurses interface with a GTKversion. No need to specify a filename in thatcase.-d device_filespecify the name of the mixer device (default is/dev/mixer ). IMPORTANT: if you use this option, specify it before any other options; it won't take effect on preceding options/commands.

35 run aumix interactively, using the default user interface
36 (GTK or ncurses, depending on the ver- sion). This is the
37 default if no options are given, but must be specified in
38 order to have aumix go into interactive mode after doing
39 things non-interactively.
40 To force use of the ncurses interface with the GTK version,
41 specify -C (no need to give a file- name).

61 The command
62
63
64 aumix -q -v75 -m 0 -c R -c+10 -m q
65 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 micro- phone.

68 The .aumixrc file containing:

70
71 vol:60:60
72 wait:5000
73 vol:50:50
74 sets the volume to 60%, waits five seconds, then reduces the volume to 50%. Note that
75 __INTERACTIVE USE__
76
77
78 If no options are given on the command line, and aumix is
79 compiled with ncurses, it will run
80 interactively.
81
82
83 __LAYOUT__
84
85
86 The left bank of controls is used for adjusting levels; the
87 right bank is for adjusting balance. Mixing channels not
88 supported by your hardware will not be shown. Mixing chan-
89 nels which are stereo-capable will have balance
90 controls.
91
92
93 __KEYS__
94
95
96 The following keys control aumix in interactive
97 mode:
98 page up, page down, up and down cursor
99
100
101 select a new control.Tab, Enter, 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.
102
103
104 Space
105 toggles between record and play for controls which are
106 capable of this.

144
145
146 ^Z, ^D and ^C also have their normal function (the screen is
147 refreshed when aumix is brought to the
148 foreground).
149
150
151 __MOUSE__
152 In interactive mode, aumix can accept input from the mouse
153 if gpm(8) is running and aumix is compiled with
154 gpm(8) sup- port. If gpm is not running but gpm
155 support is included, the message mouse off will
156 appear at the top of the screen, and only keyboard input
157 will be accepted. With gpm(8) run- ning, most
158 functions can be performed through the mouse. The mouse is
159 active whenever one of its buttons is held down. While
160 active, it works in the following ways:
161 over a control track, it sets the control to match the
162 position of the mouse cursor.
163 over a record/play indicator, it toggles the record/play
164 state.
165 over the Quit, Load, Save,
166 Keys, Mute, Only, or
167 Undo labels at the top of the screen, it causes
168 those actions to take place.
169
170
171 __ENVIRONMENT__
172
173
174 The HOME variable is used. When aumix is compiled
175 with GTK+ support, DISPLAY is checked, and if set
176 is used. LANG is used when aumix the ncurses screen
177 is displayed.
178 __FILES__
179
180
181 Saved settings for the mixer are kept in the
182 /etc/aumixrc and $HOME/.aumixrc files, but
183 can be kept anywhere if speci- fied explicitly. Color
184 schemes are normally kept in the directory given by
185 DATADIR at compilation time, but are preferentially
186 loaded from the current directory and can be kept anywhere
187 so long as the path to them is specified. The format of
188 these files is:
189
190
191 item foreground background
192
193
194 where item is one of active, axis,
195 handle, menu, play,
196 record, or track and foreground and
197 background are one of black, red,
198 green, yellow, blue,
199 magenta, cyan, or white. The
200 words should be separated by whitespace and can be upper-,
201 lower-, or mixed-case. Lines not matching all these
202 conditions are ignored. Some samples of color schemes are
203 provided, named after the sort of terminal where they should
204 be most suitable.
205
206
207 If either foreground or background is given as -,
208 then the default color for that is used. If aumix is linked
209 against ncurses, then the terminal's default fore or
210 background will be used; else the default foreground is
211 white and the default background is black.
212
213
214 An xpm icon is provided.
215 __VERSION__
216
217
218 This page corresponds to version 2.7.
219 __BUGS__
220
221
222 Suspending with ^Z may make the terminal difficult to
223 use.

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