I've updated to the 27352 mythbuntu auto-build.

What I've noticed: when I scan and use ALSA:hdmi:CARD=NVidia_1 I get
the following frontend output

2010-11-27 12:16:34.373 AFD: Opened codec 0x971a5b90, id(H264) type(Video)
2010-11-27 12:16:34.374 AFD: codec AC3 has 1 channels
2010-11-27 12:16:34.375 AFD: Opened codec 0x971b1d30, id(AC3) type(Audio)
2010-11-27 12:16:34.588 AO: Opening audio device 'hdmi:CARD=NVidia_1'
ch 2(1) sr 48000 sf signed 16 bit reenc 0
2010-11-27 12:16:34.617 AudioPlayer: Enabling Audio

but no sound over HDMI

If I go back to use the old ALSA:hw:1,7 I get sound, AC3/DTS look to
work properly, and my HD music plays properly. So it looks like it's
all good minus the general ALSA issue with device scanning, but thats
not your issue to deal with.

Thanks JYA!
