headphone jack displaying red light

It means your digital audio out has switched on. You can insert a plastic toothpick in the hole and try and switch it off. The switch should be at the 3 o'clock position and go towards the 6 o'clock position. Some people also have had luck inserting their headphone jack and pulling out a few times. Another recent report was that inserting the headphone jack and turning it in the hole helped.

If your not successful or uncomfortable doing this you need to contact Apple about service.

Your eyes are better than mine. All I know is there has been success using the 3 o'clock position for the switch and clicking it towards the 6 o'clock position. I'm not sure what you mean by hours and minutes?

there are no hours or minutes, there is a switch in the port, and changing it from the 90 degree angle (or 3 o'clock) position to 180 degree (or 6 o'clock) position will fix your problem
hope this helps!

This just *****, should be addressed and most certainly should be covered beyond 1 year warranty since it is DEFINITELY caused by the OSX update!!!!!!!!!!!!

Thanks guys, used a 1.2mm precision screw driver to locate a little tab in the headphone jack which I found in the 9 o'clock position, I put slight pressure on it downward toward the 6 o'clock position...didn't really seem to move, but the light suddenly shut off and PRESTO! When I pressed the volume button sound filled my ears like a sweet violin. Wow, I was really frustrated by all of this. THANKS ALOT EVERYONE!!!!!!

Hi everyone.

I've had this same problem happen to me just now. I'm unable to find this "switch" you are all talking about. If I hold the headphone jack in the audio output just the right way, my internal speakers work. If I place a small metal rod into the output just the right way, the light will go off (while i'm holding it in, of course); but I can't seem to fix the problem.

What is this "switch"?
Where is it? How come some switches are in different places? 3:00 and 9:00? But it should be in the 6:00 position?

HELP!!
i can't afford to send my macbook in
=(

Thank you MORT

i had this problem and found a sowing pin and had a poke around, i managed to find the button/ switch and my wife managed to move it.

it takes a bit of VERY carefully looking and VERY VERY careful poking!

thanks again

Man, someone should e-mail this to Apple Care guys.

I called them in Brazil and US and none could give me at least an explanation about why there was a red light coming out from audio jack. The solution both gave me was "take it to the nearest Apple Service Center".

What none have asked me was where this "nearest center" was. I'd be very angry if I had made this 500km trip to see the guy fixing my MB with a toothpick.

I'm very thankful for your help on this.

Cheers.

This is an actual hardware switch, so it is DEFINITELY NOT caused by a software update. Its usually caused by a small ammount of lint or something getting in the headphone jack and prohibiting the switch from turning off.

DEFINITELY not caused by any OS X updatess.

I tried sticking a tooth from a comb into the headphone socket and basically twizzled it about a few times, not particularly delicately, and it turned the light off and the sound now works properly. I don't know if this is unwise or could damage the socket or what, but it's worked for me so thanks for the help evenyone!
