Sure,
There was very little work involved in setting up HDMI audio:
Here's my /etc/asound.conf [0] which allows you to leave MythTV set to
play to the alsa default output. By doing it this way it also means
other apps that use alsa will default to HDMI out too (e.g. mplayer).
To make sure that you can get to this stage I've attached my `aplay
-l`[1] and `aplay -L`[2] outputs to compare to yours.

My xorg.conf[3] is also attached, I luckily commented in where some of
the options came from back when I added them.

I don't have numbers on cpu usage for HD at the moment.. I'll check it
out soonish when I find some time.

Hope that helps
Cheers,
Owen.
