So I've been noticing this problem a few weeks back now until recently noticing it more a couple days back. My speakers seem to get that rattle sound that you get when turning up low quality speakers to max when listening to certain types of songs maybe with stronger bass, but the problem is far more apparent during youtube videos where maybe sound quality isn't the best. Is this normal for the MBA? Or should i go take it up to the genius? I'm starting to guess it might be popped speakers. I've only had this laptop for about almost a month.
