[mythtv-users] SPDIF Audio Stopped Working

[Jay Foster]

I'm running Mythbuntu 8.10 0.21-fixes.  I've been using the SPDIF audio 
output for both AC3 5.1 audio and 2ch audio.  For some reason, the 2ch 
audio output has gone silent.  AC3 5.1 audio still works.

This is true for both mythmusic and mythvideo (mplayer).  When playing 
2ch audio programs, I do get sound out of the analog line out.  I used 
to get it out the SPDIF too.

Any ideas?
Jay
