| I'm wondering about the ac97 codec message?
The ac97 code has a table of codecs that provide the name and optionally a
function pointer to a vendor specific initialization routine. On RELENG_4,
the AD1985 does not have an entry, so the codec is indicated as "unknown" with
the relevant codec id. The latter is useful for diagnostics.
If you want a short-term fix you can edit the codec table in
${SRC}/sys/dev/sound/pcm/ac97.c. We're about due for a syncing of the ac97
codec between RELENG_4 and HEAD, which would fix the message for this and
quite a few other codecs.
