Hmm.  My kernel config was:

device     pcm0 at isa? irq 10 drq 1 flags 0x0
device     sbc0    at isa? port 0x220 irq 5 drq 1 flags 0x15

which gave the previously reported output.  I changed my
kernel config to:

device      pcm
device      sbc

and it changed the output of sndstat to:

FreeBSD Audio Driver (newpcm) Oct  6 2001 20:37:13
Installed devices:
pcm0: <CS423x> at io 0x530 irq 5 drq 1:0 (1p/1r/0v channels duplex)

In other words, it's recognizing my sound chip not as a sound-blaster
compatible (which I believe it is, as the VOXWARE drivers worked for it),
but as what it is specifically.  In doing the problem with the mixer
seems to have gone away.  I don't have a main volume channel, but the
PCM channel is working to adjust the volume.

Thanks for the input!
