After upgrading from 20 to 21 I have the same problem - I think.

Everything is working, there's light at the SPDIF transmitter, and, like 
Matt, digitally recorded sound is working great!  That is, any Over the 
Air ATSC recordings are working. Stereo and other multiple AC3 channel 
sound sounds fine.  What is not working are the old stereo recordings 
that do not have AC3 sound.

Obviously, what I lost in the upgrade was the ability to pass ordinary 
stereo sound through the SPDIF output using mplayer.  And, it sounds 
like Matt is having the same problem

My defalut video player setting is:
mplayer -fs -zoom -quiet -vo xv %s
...anyone see a problem w/that?

However, as I don't have sound for NTSC mythtv recording, I am thinking 
the problem is in a more general place than that.  Probably something to 
do w/the ALSA sound driver.

Well, I found one answer.  To get ordinary NTSC stereo to work I need to 
switch to ALSA:default to ALSA:spdif.  Now I probably need something in 
the above mplyer command to finish off my problem of no sound while 
playing non-AC3 stereo.
