you might want to try a different set of headphones, as the connectors can vary slightly in size, and this may be causing the micro switch to hang up. Also do not ever stick a needle or anything that can conduct electricity in the jack, use a Q tip with end cut off, or a wooden toothpick.

One more thing to try, go to utilities, Audio/MIDI Set up, click output tab, highlight built-in output, then for source select Internal Speakers. Hope this helps. If you still have issues go to the Apple store, they diagnose problems for free, and if it is still under wrrenty, or you have AppleCare they will fix it. Sorry I could not be of any help to you. SJP

I don't know what P-R means, if you mean a pram reset it goes like this: Power down, power back up holding the following keys: OPTION, COMMAND, P,R (no commas) press these keys before the start up chime. Continue to hold these keys till you hear the start chime 2 times, then release. Check your audio output, then reboot. Check again. if no joy take to Apple store. All the best.
