No sound on speakers

[Richardsimon]

I wanted to show my buddy the Magicjack on his computer. Long story short, it killed his speakers on his laptop. He is using VISTA. The softphone works but now there is no sound out of the laptop speakers. I unpluged the magicjack, and still no sound, I went to msconfig and stoped the start up of magicjack, still no sounds from the laptop speakers. I'm looking for idea's. Thanks
