AVR see PCM Multichannel and loose the info and drop the sound.
Can you download start.elf and fixup.dat from:
https://github.com/Hexxeh/rpi-firmware/tree/next
and replace the ones you are using. There is a fix to spdif formatting of HDMI PCM data which could improve things.
Even if it doesn't, the new firmware has some config options that we can try to tweak some of the ways HDMI audio is clocked.
