Asrock Dual VSTA sound doesn't work

Says it needs the Microsoft bus driver. What is that?

offtopic, but otherwise how is that cpu and motherboard working out for you? do you have it overclocked to 3.5? any problems getting up that high, was it easy? thanks

As for the motherboard, I think it's a great value. I overclocked to 3.5 the first time I booted LOL. It runs great. Stock volts, stock Intel cooling.
As for the sound. It worked with another copy of windows on a different HD. It's just the HD I'm running now has a new install of XP sp2 and it doesn't work. I can put my old HD back in and no problem. So..... if anyone knows where to get, or what is this "microsoft bus driver" please let me know. Thanks
