Put these lines:
sound_load="YES"
snd_driver_load="YES"

Into the file /boot/loader.conf and then reboot.
after you reboot look at dmesg and see if it found/loaded any sound drivers
you can do this by typing in dmesg at the console and using your scroll 
lock key to move up/down OR type in "dmesg | grep pcm" you should see a 
lines like this:
pcm0: <ESS 18xx DSP> on sbc0, sbc0 is the driver it is using, now type 
in this "dmesg | grep name_of_driver" to make sure all of the sound 
stuff loaded.

now put a music cd into your cd player and type in (as root) "cdcontrol 
play" if you hear something that sounds like music your good to go, add 
the name of the driver etc. to your kernel config file and recompile 
when convenient, just remember to comment out those lines in loader.conf.

and, nevermind, im late for school
