The internal speakers on my new 4th generation Macbook pro worked just fine the first few weeks, but recently the right speaker stopped working. The only sound coming from it is a barely audible high pitched beep (over 15khz). The computer has never had any injuries and are mostly stationed on my desk. This is a pretty small problem, but it bothers me since i am an audiophile. Is there a known solution to my problem or is this a job for applecare?
