Wear and tear or substance buildup can cause an audio jack reader to stop working. When it is clear that a device is defective and when warranty options are limited, please consider assessing the audio jack in case cleaning might remove a defect. The image below represents an audio jack that is too far-worn to be considered in warranty, but some of the defects collected along the way to an ultimately destroyed condition can represent some in-warranty covered conditions and also are potentially field serviceable.

When oil, grease, grime, or another substance is built up along the surface of the audio jack, consider using a damp cloth to rub it clean. When wear and tear produces scratches or in particular, rings, then consider carefully applying sandpaper or another light abrasive to restore connection, but please note that the nickel exterior can be worn too thin for acceptable use as a consequence of doing this. Please consider in-warranty repair as the best first option for any audio jack reader defect.
