This may not be the correct device.

A reasonably painless way to determine which one you need is to build LINT
(cd /usr/src/sys/amd64/conf;make LINT), then add every device named
snd_something in LINT to your kernel config.  Rebuild the kernel,
reboot, "grep pcm /var/run/dmesg.boot".  If you have one, "cat
/dev/sndstat" and then you should be able to work out which of the snd_
devices you actually require.  If you still don't have a pcm device then
your card is unsupported.

If you don't want to go through all that, guess which device you need.
Is it a VIA sound chipset?  If so, it's probably snd_via8233 that you
need.  And so on.

Get out of that habit - MAKEDEV doesn't work in any FreeBSD > 4.x.
