audiocfg
—
configure default audio device
The audiocfg
utility helps maintaining the audio and
mixer device symlinks.
Run with “list
”, it lists
the available audio devices and shows the currently selected default audio
device. Called with “test
”, it plays a
tone of 2 seconds for each channel of the device with the index
index. Called with
“default
”, it sets the default audio
device to the one with the index index.
