Crackle and Pop

Still trying to track down the problems that I'm having capturing video with the ATI card. The system now likes to insert pops and crackles into the audio stream during capture mode. If I record audio using Cool Edit 2000 (no video capture), I get clean audio from the Line In jack. Turn around and attempt to capture video and I get crackles and pops in the audio stream of the captured file.

However, I have noticed that MSINFO32 shows that there is a bunch of stuff using IRQ9 (ATI card, the Santa Cruz sound card, my USB2 PCI card, the FastTrak100 Lite controller, and even the ethernet card... wonder if I can shove the ATI and Santa Cruz sound card onto their own IRQs.

Hmmm, no go, Win2000 seems to ignore the setting that I made in the BIOS where I specifically told PCI slot 2 to be IRQ 10. Looking at 3.7.2 of my Asus A7V266-E motherboard manual, I do see a chart that seems to indicate that slot 2 and the AGP slot share a resource. So I'm going to try moving the audio card to slot 4, which seems to have the least amount of sharing with other devices.
