| 9 | When no arguments are given, this pops up a graphical window which lets you
|
|---|
| 10 | choose the audio input and output devices, and set the output volume.
|
|---|
| 11 |
|
|---|
| 12 | This program can be driven via the command line, and when done so, no window
|
|---|
| 13 | pops 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 |
|
|---|
| 20 | The 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 |
|
|---|
| 32 | Other 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.
