so my sound just randomly stops working on sites like youtube and flash players like put locker. it only recently happened when i updated my adobe flash, but failed to realize that you should uninstall the old one when you do. but i uninstalled it and reinstalled it but it didn't work. and reset my safari and empty my cache. i'm still pretty new with this mac. i have os x 10.7.5. any help would be great. thanks.
