Thanks!  The assignment of DACs depend on the pins and topology, so it
can be a bit sensitive.

Now looking more closely at both outputs, I wonder how the commit
breaks pang14.  Maybe it has a PCI SSID 2782:12c5 (or 12c3) while the
codec SSID is 2782:12b3?  If so, the patch below should fix.

Could you guys try it and verify whether it fixes for Pangolin and
doesn't break Sirius?
