I have the start of a generic audio pseudo-device driver.  It is a
transformation of the bsd_audio.c/sb.c drivers in the current system.  I
did this so that I could start developing a device driver for my own audio
hardware -- that part has been slow going so far (still trying to get my
programmed loopback tests to work).  I have not been able to test the
transformed bsd_audio/sb driver pair, since I do not have a SoundBlaster.

This driver still basically presents the same interface to the user, i.e.
basically /dev/audio.  I have some thoughts on how a /dev/audioctl
interface could be implemented.

As for libraries and user programs that is uncharted territory for me for
the time being -- I've thought of a simple play/record pair of tools.

My changes are available on request -- if you want them contact me before
friday this week (I'm out travelling right now and will be unavailable
next week).
