X-Fi Crackling/Popping Ultra-D in Processors, Motherboards and Memory Posted April 3, 2007 I have X-Fi as well and didn't got any problem so far,I was afraid to buy this card because what i heard but i have seen that it's not happend to all people. Anyway there should be two things that can happend to this: 1. Card manufactring problem 2. conflict with onboard sound card , try to disable it on BIOS(if u didn't do that so far) Oh, this is beyond stuff like that. Trust me, I (and many with me) have tried everything from changing the slot to standing on one foot and waving the left arm. It's a timing/bus-conflict and creative says manufacturers have to update their BIOS'es, which is sort of what I wanted to know: if the xfi vs nforce4 issue have been fixed through bios and if so, which versions.
