MacBook Air: audio jack left channel failing I have a MacBook Air 2012. I listen to audio by plugging EarPods into the audio jack.

This morning I noticed that I no longer have sound coming out of the left headphone. Well, There is a little, but it is &lt; 10% what it should be.  I tried a different set of headphones and got the same result.

Is there any option for repairing the headphone port? 

I'm guessing it is soldered onto the motherboard, and there will be absolutely no chance of a repair, and I will have to use a USB soundcard.

Some how my software had panned the audio to the right channel only. 

God only knows why my machine decided to pan itself fully to the right!?

Anyway, if you think you need a repair, double check it's not software as I found on the Apple discussions.
