I applied Tom Lees' ISA PnP patch (as I mentioned, my sound card uses
PnP), then configured sound like this:
CONFIG_SOUND=y
CONFIG_SB=y
SBC_BASE=220
SBC_IRQ=5
SBC_DMA=1
SB_DMA2=5
SB_MPU_BASE=330
SB_MPU_IRQ=-1
CONFIG_ADLIB=m
CONFIG_SOFTOSS=m
CONFIG_YM3812=m
CONFIG_LOWLEVEL_SOUND=y
CONFIG_AWE32_SYNTH=y
Here is the dmesg output:

loading device 'eth1'...
I can run timidity 0.2i (which uses /dev/dsp), playmidi 2.4 with AWE32
support (using /dev/sequencer), and aumix (/dev/mixer) all at the same
time with no problems, just the same as when I was using modular sound.
However, when I put the computer in single-user mode and catted a file to
/dev/audio, it locked up, just the same as when I was using modular sound.
The file played for about a minute, the same as before. I haven't tried
my zwav script again, but I will if someone asks. I've noticed that the
LED indicating IDE activity has been "stuck" on during several of these
lockups. The .au file is on /dev/hda, and the .wav.gz file is on
/dev/hdc. I haven't loaded the opl3 or softoss2 modules.
I made a diff of my drivers/sound directory versus a clean 2.1.77 (okay,
one from which dmabuf.c.old had been removed) and made it available at
http://www.jpj.net/~trevor/sound-2.1.77.diff. It consists mostly of the
ioctl patch several people posted, along with fallout from the ISA PnP
patch and from Michael Chastain's CONFIG_SMP patch, but I made some
changes to dev_table.c, sb_mixer.h and sys_timer.c.
During compilation, I get these sound-related warnings, which appeared
only after I applied the PnP patch and configured sound as partly
non-modular:
dev_table.h:396: warning: initialization from incompatible pointer type
dev_table.h:397: warning: initialization from incompatible pointer type
