Most likely not the soundcard but an irq-sharing issue - once the

Huh? With APIC selected in bios XP gives you 23 IRQ's. XP handles IRQ
addressing just fine. What OS do you recommend we run our games on?

There are many motherboards that have two or more slots tied together so
that both share the same interrupt. The operating system cannot
override this.

As for XP handling IRQ addressing just fine, there is a very special
place in Hell reserved for whoever was responsible for implementing Plug
and Pray without manual overrides. You're basically forced to trust an
Artificial Stupidity, which is always an unwise course of action.


In win95b/win98 and ME you can revert to none ACPI usage of IRQs quite
easily like this,

and then have more control of IRQ assigning.

Don't know for XP so be a,"Guinea Pig"?

Personally I don't have problems with IRQ sharing.This is not MS's
fault usually but lazy or inept hardware makers who don't make their
devices correctly.
Also a common mistake as in the posts is to trust Plug in and
Praysic but this can be defeated and still be enabled as per,
http://www.geocities.com/sheppola/drivers.html

Note:
Mother boards that allow the reservation of IRQs for specific PCI
slots are overridden by ACPI in the O/S if it's enabled.
