Hi guys. This problem I have been having has been driving me absolutely nuts for the past month or so. I have tried almost everything i could possibly think of to fix it. Here's whats happening. I have an audigy x-fi platnium sound card and whenever i play any sort of music, it crackles and pops and skips. I have checked the drivers, sampling rate, digital output mode, etc. The only thing I can think of is a possible IRQ conflict. All of my PCI slots in my mobo are filled and I recently installed a PCI SATA controller. I can't remember if the problem started before installing that or not. When I look at my system information, i can see that the card and the audigy sound card are sharing the same IRQ channel 16. The system doesn't report any conflicts. Should I try switching the audigy to an open IRQ channel all by itself and see if that helps. Any expert advice would be great. Thanks!
