Just a follow-up:  I installed TVTime just for the hell of it, and I 
don't have any sound coming out of it either.  I'm going to try 
recording something later and then play it back.  If the "no sound" 
issue is only on the "Watch TV" portion of Myth, I'm OK with that since 
I never use that.  As long as I have sound when I play recordings back, 
then I'm fine.

In the meantime, any other ideas on the aplay and amixer output that was 
requested a few days ago?

Thanks,
Harry
