Hideous audio crackling and popping under Windows 7: "SOLVED"

Hi all.

The main reason I installed Boot Camp in the first place was to run audio apps like Sound Forge natively. But I'm finding the audio playback under Windows 7 64-bit to be pathetic and wholly unusable. With no other applications running on my late-2008 iMac with 4 GB of RAM, I can't play any audio without massive snapping and popping about once per second. Useless. I had far better audio than this on Pentium machines in the '90s.

I have the latest Realtek driver installed.

The problem occurs no matter what the source, through both the analog and digital outputs.

UPDATE: Found the problem (thanks to this post: http://brianreiter.org/2010/08/16/fixed-boot-camp-audio-pops-and-crackles-with-w indows-7-x64 ).

It's the wireless networking driver. Pretty pathetic, but you have to disable the wireless adapter under Windows if you want usable audio under Boot Camp.
