Not sure if this still works... The cdcontrol utility
was used for decades with the acd driver (ATAPI), and
that supported the command to play audio CDs (usually
with output through the internally wired CD Audio
The command of course expects /dev/cd0 (full path name),
which should be the default anyway. You can check it:
# cdcontrol eject
Does the drive open? If yes, you don't need to specify
the device. :-)
You can also set a device with $CDROM in your environment;
see "man cdcontrol" for details.

# pcicontrol -lv | less
and see if the system detects your sound hardware as
you would expect. Next, check:
# dmesg | grep "pcm"
as well as
# cat /dev/sndstat
You should also verify that the corresponding mixer
devices appear in /dev (usually mixer0, maybe more).
>From your above output, it seems that the device has
been recognized correctly, so now check for several
1. Is the mixer set correctly?
2. Is the device using the correct output unit (if there
is more than one)?
3. Are you connecting your speakers / headphones /
amplifier to the correct output?
# mixer -f /dev/mixer0
# sysctl -a | grep "snd"
will tell you most things, the rest is done with eyes. ;-)
