The initialisation path for the IGP version of the chipset is missing a call to r600_audio_init, so audio isn't enabled on those chipsets.
I've attached a patch to fix the problem, but beside from a compile check its completely untestet since i don't have access to an IGP version of the chipset.
awesome. i'll give it a whirl and get back to you.
