As much as I hated when people did this to me... it worked when I needed

Also, unless someone on this list has had the exact same issue (check by 
searching the list as 
http://www.gossamer-threads.com/lists/mythtv/users/) you're probably not 
going to get the response you're looking for... in the event you still 
have issues, try getting on the ALSA-User list and asking your question.
