FYI here is a posting on H55 audio problem:

I'm contacting the author and will keep you informed on any progress.

Ironlake should support hardware channel mapping, the current ALSA
code should just work for it.

ALSA currently don't have the HDMI High Bit Rate (HBR) support,
so I'm not sure if DTS-HD or TrueHD can be played.

If HBR is a requirement to play them, I'll work on an ALSA patch to
do HBR.

Thanks,
