With it jumping back to the internal speaker, i believe there is a bad connection on the audio jack, either where it connects to the headphones, or where it is soldered on the board (or flex cable, however it is attached). Especially if you can wiggle it. Also with wanting to remove the built in speaker functionality, why dont you just remove the speakers all together. Desolder them? Should be fairly cut and dry....
