[mythtv-users] AC97 in only one speaker

I'm glad to hear I'm not alone on this one.  I've been really racking my 
brain on this one.  A new test I tried, when running TvTime and also 
running "aplay /dev/dsp" at the same time and muting the line in (thus 
only playing the recorded audio), it DOES play in both speakers and 
there are no "snaps" "crackles" or "pops" in the audio, just a mild 
hiss.  However, once I switch to the TV in MythTV, it goes to one 
speaker and the rice crispy effect is back.  Anyone with any ideas let 
me know.  I'll try anything at this point.
