NAME
audiocfg -- configure default audio device
SYNOPSIS
audiocfg list [index]
audiocfg default index
audiocfg set index direction encoding precision channels sample_rate
audiocfg test index
DESCRIPTION
The audiocfg utility helps maintaining the audio and mixer device sym-
links.
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 repre-
sented 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 for-
mat you want to set. These parameters must be selected from the candi-
dates 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.
