Try this (taken from the handbook):
// load all the sound drivers
# kldload snd_driver
// see which one worked
# cat /dev/sndstat
Here's what got loaded:
# kldstat

And here's what I needed:
# cat /dev/sndstat
FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <Intel ICH6 (82801FB)> at io 0xc8000800, 0xc8000400 irq 22 bufsz 16384
kld snd_ich (1p/1r/0v channels duplex default)
So, I added the following to loader.conf:
# cat /boot/loader.conf
...
#sound driver
snd_ich_load="YES"
