Some HDA chips are connected in "compatibility mode", some are
connected in HDA mode. So for some chips it works to add the ID, and
for some chips it just doesn't work, since the hardware (as in "traces
on the board") can't be configured to do both.

An interested soul may want to have a look at the much improved
soundsystem in FreeBSD-current. I'm sure a lot of bugfixes and
can be copied verbatim.
