JYA's recent audio changes have fixed the problem for me.  You need to 
get it from https://github.com/jyavenard/mythtv (I don't use his PPA, so 
I don't know if it's available there too).  I also don't know if his 
changes have been committed to trunk in the main git repo, since I run 
0.24-fixes and not trunk (or master in git-speak).

Hope this helps!
