This happened suddenly. Sometimes I plug in headphones, sometimes I plug in an audio system, into the small jack socket on my MB Pro 13" (November 2009).
Just today, this has stopped working and I can't listen to anything through my headphone or through my audio system.
Would this be because the socket has become defective, or is it a software issue?
All suggestions welcome.

Try a PRAM reset:

If that fails an appointment at an Apple store genius bar is a good idea.

P.S. the sound is fine through the inbuilt speaker on the computer.
I tried rebooting but that didn't help.
Look in the audio output port. If there is a red light, then the switch id stuck. Insert your phone plug a few times. If no success, try jiggling a toothpick or similar object inside. If still no success, go to the Apple store.

Nope - no red light. So I didn't jiggle anything inside the port. I'm going to try resetting the PRAM.
Thanks! Resetting the PRAM did it.
Great! Or in the UK it would be Brilliant or Grand?
Ciao.
Im going to explain my scenario with my first generation white macbook 1.83ghz Core Duo.
I had been using the laptop with optical audio out and display port/hdmi adapter into my reciever for netflix viewing when the port got stuck on the optical out, I tried everything, pram reset, SMC reset, adjusting various audio output settings, toothpick and pin trick all to no avail. Finally I made a backup of all my system kexts, deleted all of the kexts and reinstalled 10.6, just reinstalling over my current installation, no format. I ran the updates to 10.6.8 and it worked.
Audio output stopped working
