I Just solved a sound problem with My Desktop. I purchased a SB PCI 128 and after installing it, I could play CD's, but the sound was very low, and when I played wav's, etc. I got alot of distortion and whistleing. At first I thought I got a bad card. It turns out that Jetway motherboards will not work with a SB PCI 128 without a bios upgrade. SO, a good hint for all, and one to add to Will's Newbie hint's. If having problems, check the Motherboard's Manufacture website for known problems.
