Plug your headphones back in. Play a bit of sound through them (e.g., a song), then stop the sound. Make sure Preferences is quit. Launch Preferences and open the Sound pane. While the Sound pane is open and set to Headphones, pull out the headphone plug from the jack. It will reset itself to "Internal Speakers" and you are good to go... this should work.as it worked for me
