It used to work for me using the Nouveau drivers but on the Ion they are
simply not fast enough to do high def video decoding.  Even at standard def
they produced a lot of tearing in the middle of the screen, most noticeable in
pan shots.  I installed the NVidia drivers and they solved that; but then HDMI
sound wouldn't work.

The sound controls in MythTV indicate that the front end has a ALSA:hdmi
device that it can put sound to.  This also indicates that it can take a
variety of digital inputs - e.g. Dolby DTS.  I've tried turning all those off,
all on and only Dolby DTS on; no sound comes out of the TV in any of those
configurations.  The standard ALSA analogue audio, and the PulseAudio output,
work - but they output to the standard audio output, not the HDMI.

What have you done with your config, Steve?
