Audio CDs may already work (assuming your mixer defaults to
sane values). Try inserting a CD and running "cdcontrol"

If it's going to work, then it will work by just adding "device pcm"
to the kernel.
A quicker and easier way might be to run "kldload snd_pcm" as root.
To see if it worked, run dmesg immediatly afteward and look for the
pcm: xxxxxx messages. If it says something like:
pcmN: <OPL3-SA3> port blah irq blah at device blah on blah then it
worked.
You will most likely have to build the audio devices as well.
Just cd /dev and run ./MAKEDEV sndN where N is the same as was displayed
on the pcm line in the dmesg.
You can see what your card can do then by typing cat /dev/sndstat
You can change the mixer settings by running mixer(8).
Good luck.
