Today I was listening to some music with my speakers hooked up to my mbp. I accidentally bumped it (not very hard...enough to slide it an inch on my desk) and it immediately shut off on its own. When I restarted it, all the audio coming from the output was (and still is) distorted with a crackling noise and bass also gets cut out. Is it possible I damaged the physical input/output and need to replace it? The wires didn't snag or put any tension on it so I can't see how it could break. Also the built in speakers had audio distortion but it just went away after a few minutes. I reinstalled OS X Lion with the recovery partition and it didn't fix the issue.
