Actually, no.
There are four IRQ lines on the PCI bus, which map in an implementation-dependent way to hardware interrupts.

Interesting...
The systems I've used only showed one IRQ being used by the devices on the PCI Bus, so that's how I drew my conclusion.

Try changing slots to one where IRQ's are not shared with other devices. I don't know why but the X-Fi seems to dislike IRQ sharing. Also, make sure you have the latest drivers. There was a fix some time ago for systems with 4GB or more of RAM.

Taddeusz wrote:Many, but not all, motherboard manuals will tell you which PCI slots share IRQ's with what onboard devices. When I originally bought my X-Fi I had an Asus A8N-E, an nForce 4 Ultra based motherboard. Unbeknownst to me at the time, the nForce 4 is notorious for X-Fi incompatibilities. From the second I installed the card I had terrible crackling problems all the way to no audio. After doing some research along with some trial and error I moved the card to a slot where it wasn't sharing an IRQ. The slot I originally installed it in was being shared by the video card of all things. Once I changed the card to the other slot everything cleared up and I had flawless audio.
