Mid-2012 MacBook Air's headphone jack problem

Sounds like the headphone jack has a short in it. Get your MBA to a Genius bar for a full diagnosis.

I have same issue. Ive found tiling the laptop from side to side can restore sound. A bit of a thump near the headphone jack has the same result. Seems the jack is faulty. When I plugg in the headphones it doesnt feel right. Quite hard to push in and no definite click feel when it goes in.

I have had the same problem, and I asked a guy who works in authorized apple service in my country and he said to check the balance in system preferences>sound>output but it was in the middle than I realized that I have to plug in headphones and the balance moved automaticly on the right side then I put it back and here we go fixed both sides were working perfectly 🙂 I hope this will help 🙂

Many thanks for this! I had exactly the same problem, and this was the solution! I have no idea why it chose to reset the balance all the way to the right.

Thanks,

I had the same problem, sounded awful, I checked what you said and I had the same issue, balance all the way to the right. All fixed now.

Thanks loads

This happens to me all the time. I'm constantly having to re-Balance my Headphone Output to the Center. It's moving on its own somehow. What's the **** is going on?!?!

This just happened to me again yesterday... if you are experiencing it a lot, you are actually in a good position to figure out scientifically what causes it.

I can't figure it out.

• I am using Boom app
• it is OS X mavericks
• I was trying out different headphones at the time

but I'm sure I have switched headphones in the past tons of times without getting it.

I wonder if something is making the OS think that the output device is mono... like the plug causing some sort of short circuit on its way into the socket...

I started doubting me new EarPods and then I've stumbled upon your suggestion. Thanks. This helped me.
