I saw this question when it was first posted before your reply and
didn't answer cause it thought it would have been pretty much a FAQ.
But based on lack of responce, and this pretty much incorrect responce I
will step in.
Basicly this error I consider a bug in the sound config defaults
(Windows has this same problem with it's defaults). The PAS16 is hard
wired to use IRQ10 for it's SCSI controler. So you can't do anything
about that. But it's sound interupts are soft-configured, no jumpers at
all. The only jumpers on the card are the base address (for multiple
cards), and DMA channel sharing (don't touch, only for the oldest mostly
incompatible 386s (I have a list if anyone really wants it)).
O'kay now for the solution. It is quite simple, just rebuild your
kernel (or modules). Do a `make config` and when you get to the sound
card settings, specificly the PAS16 IRQ setting pick something other
than the default, 10. My manual lists these defaults:
ProAudio Spectrum 16
Port: 338
DMA: 3
IRQ: 7
Soundblaster Emulation:
Port: 220
DMA: 1
IRQ: 5
With those settings everything should work fine. (I still can't mount
my CD-ROM drive for some reason, but it isn't an IRQ conflict. I
believe it is my cheap drive.)
If someone knows the author of the sound config, and would like to tell
them to change the default IRQ away from 10 perhaps this problem can be
avoided in the future.
