Hello again. I'm into my second week with my mbp. Its running great, no problems, except for a possible one. When I start listening to audio, there is a soft, but noticeable, "click/pop" sound before the audio starts. I think this sound only comes from the left speaker. I haven't notice this until today. Can anyone confirm if this is a problem, and if it is, is it a serious one? Thanks. EDIT: This sound also occurs randomly when the speakers are not in use. I have the penry 15" base model. EDIT2: This sound occurs while the audio is playing, but rarely.
