Are you using the TV-out of the PVR-350?  If so, the sound is probably 
coming out of your -350 instead of your sound card.  MythMusic will use 
your sound card, though, and so will MythVideo (unless you're using a 
patched mplayer).

Scan the list archives for various ways to address this issue; I don't 
have a PVR-350 so I'm not familiar with the specifics.
