Hi all After upgrading to ML, I've encountered a bug where the sound after a bootup is extremely loud and only plays on the left side. This is very very annoying as I use headphones and my left ear does not like this. When I go into the Sound page of System Preferences I can see the balance is indeed almost completely to the left. So I adjust it and it's all good again. But as I don't want any eardamage and often forget to check it (I shouldn't check it in the first place), is this a known bug or is there anything I can do about it? Never had this with Lion. Thanks!
