I have a KT133, and they have a famous interrupt problem. That is, at least with my M-Audio Delta 44, unless I set the PCI Latency to 0 and turn off PCI Delayed Transaction in the BIOS, I get crackle, crackle, crackle. And sometimes, even if I do all that, I still get the crackle. It happened in Windows 2000, too. -Max
