[mythtv-users] Sound Problem - Any Help Appreciated (A Little OT, but not much)

I have RH9 and SB Live on two mythbackends working fine under oss.  I
have switched to oss a long time ago before alsa seemed to break sb live
support(i think i read that somewhere).  I have never looked back.  I
get the added functionality of emu-dspmgr which allowed me to control
where to send the audio output (front or rear speakers in one machine,
front or digital in the other) plus I got ac3 pass through working. 
This is all done without loading or unloading the driver so myth can be
happily recording and not be interrupted.  search for emu10k1 drivers in
google.
