I plugged my headphones into my Mac earlier to listen to some music. Almost immediately, I noticed a sort of white noise in the background. Then, every time I would get a message on Skype or Facebook or something of that sort, the white noise would be louder and there would also be weird noises that I don't really know how to explain. They sound kind of like..chirps and buzzes? I'm not really sure how to explain them. I tried changing the alert sound effects and everything, but nothing stopped it except for taking my headphones out. And I also noticed my trash doesn't make a sound anymore when I empty it, both with and without headphones.
I'm not sure if this is a problem with my headphones or my Mac itself, but some input would be greatly appreciated. My headphones seem to be working fine on my mom's Windows computer..

MacBook, Mac OS X (10.5.8)

    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.

    I had the same issue.

     

    The fix for me was to go to Utilities/Audio MIDI setup and configure the "Build-in Output" output format to "2ch-32bit Float".  In fact 2ch-24bit Integer made the hiss almost disappear already.

     

    On my system, it was set to 2ch-16bit Integer.

    The problem remains at the latest macbooks and the up-to-date OS. I have the same issue on MacBook Pro 13.3 Retina.
