9When no arguments are given, this pops up a graphical window which lets you
10choose the audio input and output devices, and set the output volume.
11
12This program can be driven via the command line, and when done so, no window
13pops up. Most options have the general form:
14
15 --device[={0,1}]
16 -d[={0,1}]
17 Set the I/O device. With no value, it toggles the specified device.
18 With a value, 0 turns the device off and 1 turns the device on.
19
20The list of devices and their short options are:
21
22 (input)
23 microphone -- m
24 linein -- i
25 cd -- c
26
27 (output)
28 headphones -- p
29 speaker -- s
30 lineout -- o
31
32Other options are:
33
34 --gain volume
35 -g volume
36 Sets the output gain to the specified volume, which must be an integer
37 in the range [%(MIN_GAIN)s..%(MAX_GAIN)s]
38
39 --version
40 -v
41 Print the version number and exit.
42
43 --help
44 -h
45 Print this message and exit.
