I've got the same problem. It goes away if I uncheck the option to 
upconvert stereo to 5.1 audio. FWIW, that's been a bit dodgey for me 
since upgrading to 0.24, anyhow -- it works fine for a few minutes, and 
then I get a brief audio glitch (a brief crackle, or transfer of sound 
from the front to rear speakers for a fraction of a second, or 
whatever). Then it works fine, followed by a brief glitch, and so on. 
Thus, I've been relying on my receiver's upmix features since the 0.24 
upgrade, despite the fact that my receiver tends to change modes 
whenever I pause or fast forward. The only reason I know about the issue 
is that I tried the MythTV upmix feature after my last MythTV update. 
(I'm also using the JYA builds.)
