17 day old 15" MacBook Pro that just came back from an Apple Repair due to a power issue, once I brought it back home and started using it, I noticed an imbalance in the speakers. I covered the left speaker and noticed that the right speaker had problems. I played with the speaker output setting and this is also the case. Called my local Apple Store and they told me to bring it back in and they'd attend to me without an appointment. Has anyone faced this problem yet? If so, what was the experience like? Did they have to send it in or were they able to replace it at the store?
