No sound after unplugging headphones

Fairly consistently, when I unplug my speakers from the headphone jack, my 2011 MacBook Pro does not switch over to the internal speakers. When this happens, nothing is amiss in the Sounds Preferences pane, but no sound comes out of the speakers... only restarting the computer resolves the problem and starts the internal speakers back on. Does this sound like a software or hardware issue? Is anyone else having this problem with the new MacBook Pro's?

Thanks for your help!

MacBook Pro, Mac OS X (10.6.7)

This problem as apparently caused by the optical sensor inside the audio jack thinking there is a headphone plugged-in, when there isn't.

Fix that worked for me: Raise the notebook and blow air into the audio connector. Do it as hard as you can.

After two blows, the speaker icon next to the clock came back to normal and the speakers began working again.

I had this issue with after unplugging an

HDMI cable, the audio got stuck. Even after selecting "Built in speakers:, I couldn't control the sound.

Ran this, and it fixed it up!

After having changed audio output settings, blowing air and restarting the MBP, only Your method with a regular headphone jack worked. Thanks, mate!
