I finally got a Sound Blaster 16 non-PnP model working. Both pcm and sbc
had to be in the old ISA:
pcm0 at isa? ...
sbc0 at isa? ...
...format. After remaking sbc0, it seemed to work fine.
On my machine, IRQ 5 was used up by the parallel port, and IRQ 7 was used
for something else (can't remember). IRQ 9 seemed to work just fine.
I've also noticed the sound card will somehow pick up whatever IRQ you assign
in the kernel config. I've changed IRQs for the card from 7 to 9 without
changing any jumpers. (Actually, there are no jumpers for IRQ on my SB16).
As a side note, has anyone played withthe Gigabyte GA-7ZX onboard sound?
I'm getting one soon, and it's a standard SB 128 chipset (I normally
wouldn't get onboard sound, but this one actually seems decent).
