Is there anything else I can do to fix it? I've also tried my headphones and had no luck with those either. Even when I go to configure my sound in the control panel (when I have a YouTube video playing) the visualisers (if thats what theyre called?) appear to be moving, as if to suggest that my system can detect the sound, but without anything actually coming out of my speakers. I downloaded a Realtek driver for Windows 7 (two in fact, alas one didn't appear to be compatible and wouldn't install) and installed it successfully. I read that MacBooks typically have Realtek sound cards in them. When I double click on one of them, it says that the device is working properly. It has this listed about 5 times in fact. When I look in the device manager and look under sound, it says the following: I think everything installed correctly except for some drivers (bluetooth etc) but the main thing that bothers me is that the sound isn't working. I have installed Windows 7 on my 2010 model MacBook Pro using Bootcamp.
