Hello,

I've finally gotten around to changing to the new(ish) PCM sound drivers
(I've been using the old VOXWARE snd dirvers), and everything on my sound card
seems to be working fine:  The kernal finds the card:

  sbc0: <SoundBlaster Pro> at port 0x220-0x22f irq 5 drq 1 flags 0x15 on isa0
  pcm1: <SB DSP 3.02> on sbc0
  pca0 at port 0x40 on isa0

(this is 4.4-stable, BTW). It's seen in sndstat:

  cat /dev/sndstat 
  FreeBSD Audio Driver (newpcm) Oct  6 2001 20:37:13
  Installed devices:
  pcm1: <SB DSP 3.02> at io 0x220 irq 5 drq 1 (1p/1r/0v channels)

and sound will play fine.  The only problem is with /dev/mixer.  If I look
at the channels:

  Mixer vol      is currently set to   0:0
  Mixer synth    is currently set to   0:0
  Mixer pcm      is currently set to   0:0
  Mixer line     is currently set to   0:0
  Mixer mic      is currently set to   0:0
  Mixer cd       is currently set to  75:75

these are not correct, as I wouldn't hear anything if they were.
When I try to change any of these values:

  mixer vol 10:10
  Setting the mixer vol to 10:10.
  mixer: WRITE_MIXER: Device not configured

Anyone have any ideas?  I can't figure out if I'm doing something wrong,
or if my rev of the SoundBlaster just isn't supported by these drivers.

Thanks in advance!
