I have the exact same issue.
Whether use my iPhone's headphones or noise cancelling Bose headphones. Same thing.
I hear lots of different noises. It is especially loud, when Safari is downloading a File.
The noises are in synch with actions taken, e.g moving the mouse, opening windows, moving them, etc.
I guess it's just poor engineering of the frontal headphone jack. Maybe an em-interference problem.
The back line out doesn't have this problem. No noise whatsoever.
