Hey guys just recently got a macbook pro for college, and i keep on hearing little speaker sounds like scratchy static coming out of the speakers when i move my mouse around or when it is just sitting idle while i read on the net. I want to know if this is a common problem or should i return it for a new one. I just got this thing literally two days ago and dont want this to become a problem in the future. I purchased a pc that had this same problem then all of a sudden one day the speakers didnt work anymore . So what do you guys think i should do?
