Hi guys, I've had my MBA for just over a month now. 1-2 weeks ago I started to have a problem with my left speaker. My assumption is that it's loose inside the case. It makes a 'tinny' sound, sort of like aluminum foil makes when being lightly crinkled. It typically starts up when the sound is around 75% Doesn't always happen but I'd say more often than not it does. Has anyone else had this problem and if I take it to the Apple store, will they do anything about it? It sounds minor but it's impossible to tune out and is quite frustrating. Not what you expect from a $1300 laptop. Cheers.
