Well, no luck at this time fro OSS4.
Original code remounts from old OSS, and current kmix handles "per mixer 
driver" entries, so we have alsa post 0.9, sun os mixer, old oss at last.
We way behind to add support for things like pulse, windows ( don't have sure 
if it's possible), and OSS4, so we have a work to do.
There's a proposal in summer of code to revamp some of this handling code and 
touch pulse issues, and other irc genius ideas from solid guys, but not too 
much beyond that.
