Volume not working in Vista (mac)?

Hi guys,

I just installed Windows Vista on my MacBook pro, and first time everything seemed to work fine. But i couldn't open the Bootcamp application and the volume wouldn't work no matter what.
I tried putting my mac OS X install DVD back in and 'repaired', after this the Bootcamp application works, but i still can't get sound? It says no output is installed or something like that... Any ideas?
Thank you!


Sorry for bad English.

Is that 3.1?

I just looked at that, is says i need service package 2, i don't know if my Vista got that, so i went to the windows update, but it freezes every time i press update (it says it got 101 important updates?!?)

Any ides?

Well i got the newest bootcamp, and now it says there's an audio output installed, and the green bar jumps up and down when there were supposed to be sound, but still nothing?
