It's called /etc/isapnp.conf, and I did some trial-and-error uncommenting of
various lines in this file, running isapnp each time. The isapnp output
would reflect the changes, modules would reload, but I got the same errors
when trying to use sound. I'm not sure what kind of systematic approach to
take, or whether any documentation for such exists - I can't find it in the
isapnp package or the Sound-HOWTO.

I'm already using the standard kernel kernel-image-2.4.18-386, sorry, that's
what I meant by a "stock non-installation kernel", I should have been more
clear about that.

The problem I've been having here is that every time I specify any io= option
to modprobe, I get an error! For example:
retro:/# modprobe ad1848 io=0x220 irq=7
/lib/modules/2.4.18-386/kernel/drivers/sound/ad1848.o: init_module: Invalid
argument
Hint: insmod errors can be caused by incorrect module parameters, including
invalid IO or IRQ parameters
/lib/modules/2.4.18-386/kernel/drivers/sound/ad1848.o: insmod
/lib/modules/2.4.18-386/kernel/drivers/sound/ad1848.o failed
/lib/modules/2.4.18-386/kernel/drivers/sound/ad1848.o: insmod ad1848 failed
retro:/# modprobe ad1848 irq=7 dma=1 dma16-5 mpu_io=0x330
retro:/# echo /usr/share/sounds/irmp3/off.au > /dev/dsp
bash: /dev/dsp: No such device
retro:/# rmmod ad1848
retro:/# modprobe ad1848 irq=7

bash: /dev/dsp: No such device
retro:/# ls -l /dev/dsp

Sorry, what do you mean? Are you suggesting I try something here?
Many thanks,
