What is IRQ sharing, how can it be avoided and is it a problem?
A – PC compatibles running Windows can have this problem. Each PCI expansion slot is assigned an IRQ number. System resources such as IDE channels, AGP graphics, USB and Firewire also have an IRQ number. When two system resources are assigned to the same IRQ, problems can occur. Typical symptoms of an IRQ clash can include stuttering, popping sound or system slowdown/crashes during audio playback/record. Here is an edited version of a post that I made to alt.steinberg.
