	I've got a real Sound Blaster on a 3.1 system that has some
interesting problems with sound.  The first thing I tried were the voxware
drivers, with the following:
controller      snd0
device          sb0     at isa? port 0x220 irq 5 drq 1
device          sbxvi0  at isa? drq 5
device          sbmidi0 at isa? port 0x330
device          opl0    at isa? port 0x388

	It would play, sometimes ( using things like gqmpeg ), but it
would split out :
SoundBlaster: DSP Command(0xd4) timeout. IRQ conflict ?
Sound: DMA (output) timed out - IRQ/DRQ config error?

errors all over the place.  And then sometimes it just wouldn't play,
giving the same error.  So I tried the pcm driver:

device         pcm0    at isa? port 0x220 tty irq 5 drq 1 flags 0x0

with that as soon as I went into X to test it out it would lock the whole
system up, and die.  So that was bad :-(

From dmesg here's what it seems to be seeing :
sb0 at 0x220 irq 5 drq 3 on isa
snd0: <SoundBlaster Pro 3.2> 
sbxvi0 not found
sbmidi0 not found at 0x330
opl0 at 0x388 on isa
snd0: <Yamaha OPL3 FM> 

I moved the jumpers on the board to drq 3 and it still has the same
problems.  Here's what a cat /dev/sndstat comes up with :

VoxWare Sound Driver:3.5-alpha15-970902 (Wed Aug  6 22:58:35 PDT 1997
Amancio Hasty@rah.star-gate.com)
Config options: 

Installed drivers: 
Type 1: OPL-2/OPL-3 FM
Type 2: SoundBlaster
Type 6: SoundBlaster16
Type 7: SB16 MIDI


Card config: 
SoundBlaster at 0x220 irq 5 drq 3
(SoundBlaster16 at 0xffffffff irq 1 drq 5)
(SB16 MIDI at 0x330 irq 1)
OPL-2/OPL-3 FM at 0x388 irq 1

Audio devices:
0: SoundBlaster Pro 3.2

Synth devices:
0: Yamaha OPL-3

Midi devices:
0: SoundBlaster

Timers:
0: System clock

Mixers:
0: SoundBlaster


Any ideas are welcome, but since the pcm driver seems to lock things solid
trying that again isn't much of an option.  And of course under Win98 (
it's a dual boot system ) it works fine, everytime.  I suppose I could
live with the warnings/errors if it would play everytime.

Any thoughts?

Thanks.
