Vista sound problem

[Alexisus]

I upgraded to Vista about a month ago. Everything was working great. But now my sound is not working. I remember I was having Realtek on it. On Device Manager I can see High Definition Audio Device having a yellow exclamation mark. When I try to use my old driver CD, I get the message that I already have the latest version.

What is the problem with my computer then?

Update your Realtek High Definition Audio Device drivers and see if it works.

Also try to update the drivers from the motherboard's manufacturer's site and hope that to can solve your problem which may arrive in the near future.
