[mythtv-users] What could cause me to lose all audio *except* Hi-def audio?

[Phil Bridges]

For some reason, my theatre MythTV box will now *only* output Hi-Def
audio over the HDMI to my receiver.  Television shows and music have
no audio.

Here's a portion of my frontend log (-v important,general,audio):
