Thanks for the welcome and the response!

I was confused first, because I searched for it in the download section on the main page and only found a link to the Vista 64 bit audio drivers package. Now I found the download link in the forums for x86 and everything is fine.

But one thing: Realtek drivers installs besides the plain audio drivers also the audio-manager and many other programs.
Is there a way to prevent this? because I only wanna have sound, nothing else.

Well, I just wanna say, that I am missing a sound drivers package for Vista. I only see one for Win 7.

Would be great, if something like that could be provided here in the near future.
