No sound On Vista using Boot Camp 2.0

Hello,
I am new to the mac world, Need Help
I have imac 7,1.
recently installed Vista ultimate Home (32Bit) using Boot Camp 2.0 and there is no sound on Vista side and also it says that video adaptor is not compatible ( 256M ATI,RadeonHD2600 ).
How do I get the sound back and solve the video adaptor Issue, Do I need to get new drivers for both ?.

Thanks

Go to the Apple download page and download Boot Camp update 2.1 for Vista. Might solve both problems. Click on the following link to download:

It did Fixed the Video Adaptor Issue but for some reason still no Sound

Make sure the sound isn't muted. There are several places in Vista where the sound settings are applied from. To check if the sound is OK, bring up the hardware tree and see if the sound device is working.

Here's how:

download the sounds drivers from the website and install them on my own. i did that for my new aluninum unibody MBP and it fixed the sound. my drivers were from realtek.com i don't know if your soundcard is the same. It probably is. so try downloading from there.
