AUDIOCFG(1) BSD General Commands Manual AUDIOCFG(1)NAME
audiocfg -- configure default audio device
SYNOPSIS
audiocfg list
audiocfg default index
audiocfg test index
DESCRIPTION
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.
audiocfg needs access to /dev/drvctl and write access to /dev (when used with ``default'') to work.
