Hi Guys, I don't know what happened to my new MBP. For whatever reason, the sound isn't working when viewing a website, opening Entourage, getting email, etc. It does work when I play a song through iTunes and when i click the volume up/down key. So, I know the speakers aren't bad. I figure there's something unchecked somewhere... I've searched everything I know to do, but it's not working. Please help!
