Cant play games with EAX enab

Question

Hello, I was hoping someone might have some advice for me. I recently installed an Audigy 2 ZS and have been unable to play any games with EAX enabled since (including the ones that came in my Gamer bundle). About 30 seconds after starting up the game i start getting horrible high pitched noises from my speakers and the game will act visually like its a skipping DVD(lagging hard?). The noises and skipping come in waves begginning about 0 seconds apart and progessi'vely getting worse so that 2 minutes later its just all lag and sounds like someone chiseling at a chalkboard. All problems seem to go away once i have disabled EAX in the game consoles. I have run the creative updater and gotten all the newest drivers, i have tried physically moving the card to the PCI slots at either end of the stack, i've tried seemingly every combination of settings within the MediaSource panels, just for fun i even tried different speakers. i've run out of ideas and dont know what to do.

Answer 1

ok, nevermind that last post. Ive managed to get unique IRQs assigned for all devices (took some re-arranging and the discarding of a few non-essential PCI cards) but the problem remains. Also, this was probably totally unnecessary because apparently part of complying with the PCI 2. protocol (which this card says it does) is being able to share ICQs.
Also, I have tried as many of the options in that knowledge base article as i could (some of the BIOS options mentioned are not present on my system, etc) but the problem still persists.
