No Sound

[BanginJimmy]

This just started today and I cant figure it out. I have no sound for iTunes, web pages, or my start up, but I do have sound when I load MW2 and other games. Anyone have a clue what this might be or where I can look for more info on what it could be?

got it working. Uninstalled and reinstalled drivers a second time and everything is working now. I have no clue why it didnt work the first time I tried it.
