Yes, but Christopher says the card is ISA and he has ``device
pcm0....'' in the kernel, so the card should be found as pcm0, unless
it is, in fact, a PCI card.
This is based on something I read (which I can't now find; maybe it
was a thread here on -questions) and my own experience.
Originally I had an ISA Yamaha OPL3 card, ``device pcm0...'' in my
kernel and the card was indeed found as pcm0.
Recently I replaced the Yamaha with a SoundBlaster PCI128, a PCI card.
Now FreeBSD, using the *same* kernel, finds the SB as pcm1 and says
pcm0 not found:

pcm0 not found
The first time I booted with the new card all I had to do was:
# cd /dev
# ./MAKEDEV snd1
This symlinks the sound devices to <device>1 instead of <device>0:
# cd /dev
# ls -lrt

I don't think that changing the kernel config file to ``device
pcm1...' will help, I tried that in an attempt to get rid of the
``pcm0 not found'' boot message, but all that happened was that the SB
was found as pcm2 and the error changed to ``pcm1 not found''.
So, the immediate fix here is probably to run ``./MAKEDEV snd1'' in
/dev as Walter suggests. That should get sound working, but I'm still
curious as to why the card is found as pcm1. Are you sure it's an
ISA card?
The only other reason I can think of is that there is built-in sound
on the motherboard that is causing a conflict.
