"Sounds like power has been sent through the port by the amp, damaging the audio circuit.

Check around the bottom right area of the logic board, to see if anything looks burnt. Beyond this, it would need logic board diagnostics and repair, so I would highly suggest sending it to a company who does this, otherwise you will most likely waste time and money on the tools required."

Sounds like you might have damaged the headphone connector. The mac detects if a plug is in the jack and disables the internal speakers if it thinks one is in there. I had a system where the tip of the headphone jack broke off in the connector. It took a bit of work to get the tip out.
