It's odd that my sound doesn't work. Not sure if its a hardware or software issue. When the macbook pro boots up the only sound I get is the mac "chime". The thing is I don't have sound in windows 7 using bootcamp. I installed the update on my wife's macbook pro 1,1 and it works fine. I installed the update on the family's imac 4,1 and it works fine too. Any advice would be appreciated.
