I have a CE macbook 13inch and I'm not really sure about the speakers in this machine. I'm assuming there are 2 and its not just 1 speaker under there. Anyways, sound from the left side of my machine sounds very tinny and rattly. I know that's not a great description but has anyone had a busted speaker in their macbook and is that what it sounds like? I very rarely listen to music on my macbooks internal speakers so I am really not sure how it got messed up. Should I take it in to the Apple Store?
