add support for testing audio devices. the usage of audiocfg changes:
audiocfg list audiocfg default [index] audiocfg test [index] 'list' shows the available audio devices, 'default' sets the default audio device, and 'test' will play a tone for 2 seconds on each channel. example: $ ./audiocfg list 0: [*] audio0: ICH2 AC97 (2 playback channels) 1: [ ] audio1: Pseudo Audio (2 playback channels) $ ./audiocfg test 0 testing channel 0... testing channel 1... $
