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
2 GIG RAM
Terratec EWX 24/96

Much Thanks!
