I am suffering from same problem. So when I looked at motherboard technical specs, it says there are two separate audio interfaces. One for 7.1 HDMI and other 5+1 HD audio via Realtek ALC662 codec.

Accordingly I tried inserting snd_hda_intel with model=asus-mode1 to asus-mode-8 as specified in http://lxr.linux.no/#linux+v3.2.19/Documentation/sound/alsa/HD-Audio-Models.txt but aplay -l still shows only HDMI audio sink.

My question is does 2 sound interfaces mean 2 separate entries in lspci? If yes, then in my lspci -vvvnn (output attched) it shows only one entry, which must be one for HDMI sound. Could that be the problem?

Also, lshw (output attached) shows one unclaimed entry, does it have anything to do with this problem?
