There's a ton of detail why at

It's worth noting that many motherboards have a way of assigning IRQs
to particular slots in the BIOS. That might be what you need to get
IRQ 9 assigned to the sound card. If the 1010 is at 5, which is often
used for the parallel port, just about every other peripheral will be
ahead of it, taking precedence.
My bios is especially weird. It assigns irq 5 to my soundcard no
matter what slot it is in. But if i insert an scsi adapter it then gets
irq 5 no matter what slot and the soundcard gets irq3 no matter what
slot. So it seems to assign irq's based on the device class or
something. And since 3 and 5 are rather low priority irq's i kinda
dislike it.

might help if you use an XT-PIC [dunno if it's safe to use on recent
kernels, etc..]. Just tried it and it didn't do anything bad to my
system [seemingly].

for APIC systems [don't work with 2.6.x kernels according to author]
