New Macbook Pro 13'' won't recognize headphones

I bought my new Macbook Pro 13'' last month (more than two weeks ago), and for some reason started to use it yesterday. Today, when I was going to listen to music, I plugged in the headphone but the audio was played through the internal speaker. I tried another two pairs, and they won't work, either. I checked System Preferences, but there are no headphones found; the mac simply can't recognize earphones!

It's really frustrating that a brand new mac is flawed! I searched the web and it seems that many people met this problem. Some answers talked about a red light in the headphone jack... I don't quite get that... But there's no red light shining whether or not I am playing music.

Any idea? Thank you very much!

Make sure there's nothing in your audio jack and make sure your headphones work in other devices.

Yeah, of course I've checked these trivia...

Your computer is only two weeks old and still under warranty. If the headphone jack is not working take it on in to Apple and have them look at it. You should have tried out your new computer right away. Now you're probably beyond the 14 day period where you could have returned it for a new one.

Is it possible that you are sticking the headphones into the mic port? Some models have two "headphone" jacks -- input and output.

He has a MBP 13" model. Only one jack.

I brought the MBP to apple today and the problem is solved.
