I think the idea is to look at /dev/sndstat:

DING! ozzmosis at blizzard [~]cat /dev/sndstat
FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <Intel ICH2 (82801BA)> at io 0xd800, 0xdc40 irq 10 bufsz 16384 kld snd_ich (1p/1r/1v channels duplex default)
2:00 ozzmosis at blizzard [~]grep snd_ich /boot/loader.conf
snd_ich_load="YES"
