I just installed the Express34 update for my MBP and the whine has come back. Mind you, I've sent my computer in several times and have finally gotten the logic replaced with the one that doesn't whine (as much at-least). But I still used the photo-booth trick to get rid of the remaining whine, but after the update the photo-booth trick no longer works. Is there anyway to revert back to the express card software that I previously had?
