Try turning off AC3 passthrough.  Unless your broadcast content that you 
are recording in MythTV has AC3 sound, the AC3 passthrough option should 
not be checked.  By checking it, you're telling Myth that all your 
content has AC3 sound and that is should be passed through to the 
hardware.  However, if your sound is normal stereo or something other 
than AC3, then I believe that setting will result in no sound if activated.
