I've been trying to watch recordings from my HDHR device, and during
playback/watching TV I get this woodchuck noise through the speakers.  These
are the logs on the frontend:

2008-08-10 18:51:56.010 NVP: prebuffering pause

I am outputting all audio out through my Creative Soundblaster Audigy card's
digital output.  It's working for ISO movies with Dolby Digital Surround
sound and Xvid and MP3s etc.  I'm running MythBuntu 8.04 on both backend and
frontend boxes.  I'm using ALSA:default for my sound output in Myth.  Any
ideas would be appreciated.  I'd love to watch the Opening Ceremonies in
HD.  Thanks!

Jim
