In short: no don't try it.
I don't have an 965P mobo, but my guess is they are using some form of
High Definition Audio (azalia) chipset.
These usually work with the snd_hda driver, which can be loaded as a
module, see instructions here:

I believe PC-BSD has this driver as it is based on 6.2-STABLE (if not
you can download the driver from the location mentioned above). Try:

cat /dev/sndstat

and see if it reports anything. Try loading the driver by hand at the
console  and see if it reacts (cat /dev/sndstat):

kldload snd_hda

Also read the specifics on FreeBSD audio driver installation on the

IIRC, PC-BSD tries to probe all soundcards on startup, so if you have no
sound it may well be your card is unsupported.
