So, this is my first post on this forum. I've gotten quite a lot of great answers from this site, but I couldn't find an answer to this one, so I guess its time I ask a question myself. So I bought a Macbook Pro only 3 days ago, and so far I love it, I've just had one problem that started yesterday. Ranging from about 30 minutes to an hour or two apart, I'll get a random 'pop' sound through my headphones, sort of like the noise headphones make when you plug them in to the jack. Let me just clarify that it isn't my headphones, I use Sony headphones and I tried my Apple ear buds and heard the same noise several times. I've tried to pinpoint what triggers the sound, but I cant seem to get anything. Every time its happened I have just been sitting still with the macbook pro on my lap. Do you think something is wrong with the headphone port? As I said earlier in this post, I've only had it for 3 days and I've kept good care of it, so I don't think there is any way I could have damaged it. Do you think there is some way I can fix it on my own, or do you think there is something wrong with the mac I got and I should just return it and get a new one?
