the original issue is that wen using an ATI gpu with hdmi in it, rerouting the sound via the ati hdmi card doesn't work, only via the generic.

alsa devs pointed out that the ati cards listed in intel_hda.c aren't updated with latest cards due to insufficient info on about the cards.

Alex Deucher from AMD's dev answered that he will query the right team in his workplace but no response was received fro him yet.
