I have run in to this in the past and the few times I have come across it was moisture that go into the headset jack that was causing the issue. Did the device get damp or wet? Have you tried plugging in a headset and removing it? You may want to try and dry out the device a bit if it did get damp.
Let me know how it works out for you!
