這是我剛剛從Futuremark的Q&A那裡找到的
Futuremark說了很清楚了!!~
Q: I have a new motherboard with onboard soundcard. I checked the manual and it says "6-Channel AC 97 CODEC on board", still I can't run the sound tests in 3DMark03. What's wrong?

A: If your motherboard has a AC 97 sound system onboard, it doesn't natively support hardware 3D sounds. In order to get the sound tests to run, you need to get yourself a soundcard that supports 3D sounds in hardware.

單純只使用MB上無硬體DSP的AC" 97 軟體音效(..
通通無法運行Sound Test~~
