Detailed Description

Used only for alsa 0.9 and later sound. Alsa sound code is sufficiently different from the rest that trying to keep it common didn't make much sense.

int audio_play	(	int	buffer,
		int	off
	)

Play a sound using the Alsa9 sound system.

Does the actual task of writing the data to the socket. The ALSA write logic is a bit odd, in that the count you pass in is not the number of bytes you are writing, but the number of samples you are writing. Thus, if you have stereo with 1 byte/channel, you'd divide the number by 2. If you have 16 bit audio with stereo, you'd divide the number by 4.
