I just picked up this card, and am having problems with popping and crackle, particularly (but not limited to) mp3 listening. I've tried using the "new" beta drivers, the 1.57 regular drivers, making sure it's on its on own irq, and switching pci slots, but I still get crackle, particularly when my system is under heavy load. Anyone else have these problems? And has successfully resolved them? I'm running Windows XP Professional. I'd take it back, but i got the last one at Best Buy 🙁 Thanks in advance for any help you guys can provide!
