Macbook Pro 6,2 No Audio Solution
The only way i could get the sound to work after hours of going through forums and all that jazz was thanks to this website http://realitypod.com/2010/07/macbook-pro-no-sound-in-windows-7-final-fix/
SOOOO HAPPPY 🙂 sound works great now.
if this helps just one person then im happy
