Repairing the mysteriously muted Mac
Posted 22 March 2013 - 03:52 AM
Both channels play out of the internal speakers normally when the headphone jack has nothing plugged into it.

Has anyone else had a heat related sound problem?

FIX: Similar to the suggestion in the article, unplugging the speaker cable from the Mac's headphone jack and plugging it back has always worked but it only takes 1x for it to work (for me).
One of the "fun" outcomes is that when I disconnect the cable from the jack there's a flood of "backed up" sound effects that play all at once!

Try resetting the PRAM and NVRAM:
Failing that, take it to an Apple Genius Bar or Apple authorized repair facility nearby. The one-year warranty (or three-year warranty if you bought Apple Care) is still in effect, it's a no-cost repair. If nothing is nearby, call Apple Support:

Apologies, meant to say PRAM/NVRAM and SMC!

I got great help, although embarrassing from Apple Care.
Thanks to all who took the time to recommend solutions.
