The headphone jack on my MacBook Pro stopped working. It was working fine, then just spontaneously stopped while I was using external speakers plugged into the output jack. Now, neither speakers nor 3 different headphones have sound. The internal speaker on my MacBook Pro still works.
I've had similar issues and restarting coreaudio work for me. Run this in a terminal (you might be prompted for your password).
sudo pkill coreaudiod
If your curious sudo
is something used to run commands as administrator (SU-DO as in super user do) and pkill
sends signals to processes based on name, in this case coreaudiod
, which is the name of the coreaudio daemon process. When it gets a terminate signal sent by pkill it will terminate and then macOS will restart it again.

@NoamHacker Nice! Some years ago i used to have to do this all the time... now a lot less. Strange. – Mattias Wadman Oct 3 '18 at 11:17

Exactly what I was looking for, and just as I hoped, it fixed the problem! Thanks! – rinogo Feb 20 at 20:27

Worked for me when system settings and sleep didn't too, 2019 Mojave. Very strange. This happened after I changed from a bluetooth headphone to my 3.5mm. – tsujp Sep 2 at 15:07
This happened to me yesterday. I tried three different headphones.
- Go to System Preferences > Sound > Output.
- Plug your headphones in if you haven't yet.
- Look at the bottom where it says Output Volume and un-check the mute button.

Great! It fixed my issue. But how this MUTE checkbox was checked automatically. – Rakesh Juyal Aug 10 '13 at 22:54

In my case mute button was not check, but once I got into this menu, headphones started working again. Thanks! – Ivan Virabyan Jan 16 '16 at 10:48

What worked for me: mute headphones, then unmute them. Nothing else worked except this. Thanks Panusiri – xaphod Mar 16 '18 at 14:40

I had this same problem with my MacBook Pro 13" (mid-2009) running OS 10.6.8. Somewhere on the internet I found the answer. After plugging in the headphones and looking at the System Preferences/Sound, you may not see (in theis model) the option for Headphones, only for Internal Speaker. (Of course, you must first check that the audio port is selected for output, since this Mac has only a single port audio. Also, that the mute is not selected.) After seeing no Headphone option, put the Mac to sleep and wake it up again. Voila! Your headphones/external speakers will work.
Does anyone know what the permanent fix is for this problem?

This worked for me. Very strange issue. Mac OSX 10+ (Mac Book Pro Mid-2012) – Jared Burrows Jan 25 '15 at 0:14

Fixed it also for Mac OS X Yosemite on MacBook Pro Late 2013. I guess something get's reinitialized after waking up. But having it not fixed for over two and a half years... – PVitt Feb 11 '15 at 12:59

If you see red glowing light coming from it try the toothpick approach: take a toothpick and poke around in the jack until light turns off.

Just optical/analog mode ball switch gets clogged. Kind of they did in old ball mouse – iskra Mar 30 '15 at 14:19
Try resetting PRAM.
Restart your machine and hold down Command ⌘+Option ⌥+P+R all at the same time as soon as it turns on. Keep holding until it resets.
Let me tell how I solved my problem (that was: internal speakers worked whereas the headphones plugged in didn't):
I plugged in the headphones.
I pressed the "F10/Sound OnOff" key on the keyboard
That was it! The headphones worked again.
But why? To my understanding the reason is that Apple attaches the sound-on-or-off-state to the current output device.
So switching off the sound while having plugged in the headphones makes the headphones be silent. Plug them off and you will hear the internal speakers. Plug them in again (after a minute or after half a year) and they still will be silent. Because YOU switched off the sound OF THE HEADPHONES (some months ago).
(It is the same the other way round. But in that case you probably would try the F10 button ...)
(Note: you can see this behaviour also with the checked or unchecked mute button in System Preferences > Sound > Output, as mentioned in a post above. Its state depends on the selected output device.)
I'm not sure if it's a hardware issue for you; if you go under System Preferences → Sound → Output, you should see Headphones as one of the output devices. Most likely the audio is being directed to some other output device (like Soundflower or Boom). Just make sure that Headphones is selected.
In the sounds control panel with the sound output tab selected, be sure to have use audio port for output, rather than input... this was why mine was not working.
