DESCRIPTION
Theaudiocfg 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.
Run with “set”, it sets the
hardware format. The direction is represented by
either of 'p' (playback) or 'r' (record), or both of them. This indicates
the direction you want to set. The remaining parameters
encoding, precision,
channels, and sample_rate
indicate the hardware format you want to set. These parameters must be
selected from the candidates displayed by audiocfg
list.
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.
audiocfg needs access to
/dev/drvctl and write access to
/dev (when used with
“default”) to work.
