Hi there, I wonder if anyone could help..... I've got a slight problem with the headphone port on my MacBook. At the moment I have JBL creature speakers plugged in (which I've never had a problem with before, they've been in my imac G3 and in my boyfriends G4 powerbook) Whenever I'm not playing music they make a really loud popping noise, This happens when I close or open my MacBook, when I click any link on any website, be it on Safari or Firefox........Actually it does it when I'm not even doing anything!!! It doesn't however make any noise if my speakers are not plugged in (if I'm using the built in speakers) Sorry if I'm being a bit vague or if i've missed out any important information. Any ideas as to what it could be or any help in general would be very much appreciated. Thanks Cath.
