Trying with the instructions on the manpage actually disabled my
sound... then again I probably screwed up the settings (I believe it
was noted as pcm2 before??).

Here're the device.hints entries and I attached the -v boot log
snippet for the card:

hint.hdac.0.cad0.nid17.config="as=1seq=0 device=Headphones"
hint.hdac.0.cad0.nid18.config="as=2seq=0 device=Line-out"
hint.hdac.0.cad0.nid19.config="as=3seq=0 device=Speaker"
hint.hdac.0.cad0.nid20.config="as=4seq=0 device=Mic"
hint.hdac.0.cad0.nid21.config="as=5seq=0 device=Line-in"
hint.hdac.0.cad0.nid22.config="as=6seq=0 device=Line-out"
hint.hdac.0.cad0.nid23.config="as=6seq=0 device=Mic"
hint.hdac.0.cad0.nid24.config="as=6seq=0 device=CD"
hint.hdac.0.cad0.nid36.config="as=5seq=0 device=Line-out"
hint.hdac.0.cad0.nid37.config="as=6seq=0 device=Line-out"

Thanks!
