My MBA gives out squeaking sound around bass beats. Doesn't happen all the time, but when it does happen, it irritates me. When I listen to the same song on the iphone, I get a very clear sound. Can anyone do this for me? Can you listen to "Speak to me/Breathe" by Pink Floyd on your headphones / earphones if you have that track? Along with the first few heartbeats, I hear squeaking noises. Do you hear anything like that? This squeaking noise could also happen sometimes when I am minimizing / maximizing windows, or doing something processor intensive. Any ideas?
