Common problem on the MacBook Pro's. If it is, there will be a red light coming out of the audio out jack.

In that case, just unplug and plug your headphones until you get it to work. The actual cause of the problem to my knowledge is not known, but it's definitely a problem.

I have tried a dozen or times..no luck, headphones work

Try blowing it out with compressed air, assuming it's a piece of debris trapped in there.

Turn the device off that is plugged in and then restart the computer with the device plugged in. Then go to system preferences and go to sound to make sure settings are right. After that shut down computer and restart. When computer is shut down unplug headphone device before starting it back up. I had this happen to me a few times and it cleared up after doing the following. Something is definitely wrong. It does work eventually though.

Go to System Prefs > Sounds and make sure the input and output are set to "Built in"

If it's not the switch in the audio jack that's stuck and causing the issues, have you tried repairing disk permissions, resetting PRAM and SMC reset? Not sure if this will help but it couldn't hurt...
