My friend tripped over the stereo cord and snapped the tip off in the headphone port of my macbook. I'v tried for hours with tweezers but it was a clean break and there is nothing to grab, and replacing it is out of the question as that would entail getting a new logic board. Also it still recognizes the bit that is in there and will not allow me to use headphones or just play sound through the speakers. Is there a way I can disable the headphone port so that it will stop recognizing the tip of the stereo input?
