Hello all. I don't know if anyone has noticed, or that simply that my MBP has a faulty headphone jack. While I'm in OS X, I hear a "pop" noise in my headphones anytime sound comes out. When it goes from no sound to sound I hear a "pop" right before the sound is played. And it does this everytime. I haven't noticed it while running windows so maybe this is a software issue? Any input would be appreciated as I would have my MBP looked at if it is indeed just my laptop. ONLY when a new sound is played will it make that "pop" noise. For example, if I'm playing a song through iTunes, any new sound that comes up (such as from iChat) will sound fine (at least I can't hear it since there is sound already).
