Strange, it works for me.

Just a hunch, but this really sounds like a problem with your kernel
configuration, rather than a problem with the PnP stuff. Once DOS gets
the hardware configured, it ought to stay configured as long as there is
power to the board. (Or, at least, until the next hardware reset.)
Likewise for the alpha ISA PnP patches. I have a hunch that the board
really is configured OK, but your kernel is not configured right to see it.
Are you using the standard SB16 addresses and interrupts? Did you
notice the warning in "/usr/src/sys/i386/conf/LINT" about that?
# Beware! The addresses specified below are also hard-coded in
# i386/isa/sound/sound_config.h. If you change the values here, you
# must also change the values in the include file.
For what it's worth, here are the relevant lines from my own (working)
config file:
# SoundBlaster-16
controller snd0
device sb0 at isa? port 0x220 irq 7 drq 1 vector sbintr
device sbxvi0 at isa? drq 5
device sbmidi0 at isa? port 0x330
device opl0 at isa? port 0x388
Note, I disabled the parallel port interrupt (IRQ 7) to avoid a
conflict with this configuration.
Here are the probe messages I get from "dmesg":
sb0 at 0x220 irq 7 drq 1 on isa
sb0: <SoundBlaster 16 4.13>
sbxvi0 at 0x0 drq 5 on isa
sbxvo0: <SoundBlaster 16 4.13>
sbmidi0 at 0x330 on isa
<SoundBlaster MPU-401>
opl0 at 0x388 on isa
opl0: <Yamaha OPL-3 FM>
I hope this well help you to get it working.
