My son has an earlier version of the M2V & BIOS (0901) and his gets full 6ch sound.

The 1.01G, and related BIOS (1304 or 1701) do not properly handle the onboard sound: hda_codec: Unknown model for ALC660VD/ALC861VD, trying auto-probe from BIOS...

What does your /proc/asound/version say?

it seems to truely be a BIOS issue, as I don't see a difference in lspci -vvxxx between our systems:

ALSA, instead of seeing ALC660, on my box sees ALC660-VD, with very little in the way of devices (only front output) - which does not work either :(

Stumped on where to go from here...
