MOTO GP 2 (no sound)!

[jiannu]

I just installed MOTO GP 2 & I have no sound. I am running XP Pro + ATI 9700 Pro. I tried the no-cd patch but still no sound. This happened with the 1st MOTO GP, & when i installed the no-cd, there was sound. I tried to overwrite "pc data" from the original cd but it still is not working. The game looks GREAT, but with no sound, it's not enjoyable.Please help!
