Here is a somewhat detailed description of my problem:
When I disable HT in the BIOS my PC's sound playback is horrible. When Windows loads, the welcome sound is poppy and leapy. If I play a CD or wav file the sound leaps and pops as well. Strangley, the sound is fine on video playback- just not with sound files or CD playback.
I've checked for IRQ conflicts- there are none that I can see.
It looks like all audio codecs are working properly.
If I enable HT in BIOS the problem goes away completely. I'm hoping some of the gurus reading this can help me out.

Windows 2000 Pro SP4
MSI 865PE Neo2
P4 3.2
Terratec EWX 24/96

Much Thanks!
