Actually, it does play with no apparent problems when I switch the
audio back to the auto-detected iec958 device. I'll accept that it
could be a video problem, though, and if you can help me sort that out
I would be very happy. I'm using the Slim playback profile. I also
tested with Normal and some of the OpenGL profiles but they had
stuttering audio with LiveTV (using the iec958 device). I haven't
gotten VAAPI working yet (video buffering times out or something like
that) but I'm trying to knock down one problem at a time which is why
I'm starting with the sound. Another fun side effect--twice now when
entering the Audio setup, my speakers started blasting out static at
full volume. The first time it was set up with my ALSA:default device
and I thought it might have been related to my asound.conf problems,
but this most recent time it was set to the ALSA:iec958 device.

Anyway, the -v none,audio,playback log this time is way too big for an
email, so here's a pastebin (and I still had to truncate it):
http://pastebin.com/LYm7XmkT

The gist of it is a ton of lines like this:
2012-05-19 20:34:26.522989 I [11960/11960] CoreContext
mythplayer.cpp:1837 (AVSync) - Player(0): Video is 30 frames behind
audio (too slow), dropping frame to catch up.
Interspersed with:
2012-05-19 20:34:26.643303 I [11960/11960] CoreContext
mythplayer.cpp:2050 (SetBuffering) - Player(0): Waiting for video
buffers...
and occasionally:
2012-05-19 20:34:26.810285 I [11960/11960] CoreContext
mythplayer.cpp:2085 (PrebufferEnoughFrames) - Player(0): Resetting
audio buffer

Thanks,
