Can't be a GENERIC kernel, GENERIC has no sound support.  Remove any existing
drivers for sound and insert:

device		pcm
device		sbc0	at isa? port 0x220 irq 5 drq 1 flags 0x15

Recompile and install the kernel.  Reboot and note whether sbc0 or sbc1 shows
up in dmesg.  After boot, cd /dev & ./MAKEDEV snd0 or ./MAKEDEV snd1 as
appropriate.  FreeBSD properly supports the true SB 16.  Maybe you should also
delete (rm) the offending /dev/adv1.
