Sound has stopped working. Hlp!!!
 

Ok, SO I just Installed Vista on my Gateway M520 laptop, and the sound has gone missing. I was running windows xp before, and I didnt have any problems with the sound. My computer says the drivers are installed and up 2 date, I've made sure to turn up all volumes to 100%, and nothing is muted. When I go into media player, I can see the visualizations moving, as if the sound was playing, but I cant hear anything.

Can anyone help me?
