Headphone jack not working

This helped me too- what a silly procedure to have to use for simple headphones! Apple, I love you but sometimes you make me crazy. Thankfully the forum people seem to know everything. I'm grateful for the solutions.

I'm Getting Back To You I Plugged My Bose Headphones In The Jack

They Still Don't Work

Note the date. I posted in this thread because it's the first hit on Google for "macbook pro 17 headphone jack not working".

ℹ MacOS 10.10.5

When I plugged my sleeping 17" MacBook Pro into my home system (power supply, ethernet, external monitor, USB hub for keyboard/mouse, headphone jack to powered speakers), I logged in, and the sound didn't switch from internal speakers to the headphone jack. In System Preferences > Sound, the headphone option was not in the list. This has happened before.

Read the thread, no solution worked. I wanted to solve this without restarting (a Mac should not require a restart to solve a simple software issue like this), I also refused to reset SMC/NVRAM for the same reason.

The solution? With all of my stuff plugged in as stated:

1. Selected Apple Menu > Sleep.
2. Immediately after it went to sleep I clicked a key on the USB keyboard and woke it back up.
3. Headphones/Headphones Port was back in the list. Clicked it.

Worked.

17" Macbook Pro's were made by Apple weren't they? I think I ordered this one directly from Apple... Hmm. Confused.

Hope this helps someone else.

Thanks resolved my issue in the sound preferences as well

Going to sleep brought the headphones option came back for me too. Restart worked once, but issue happened later again in the same day. That's when I tried going to sleep and waking computer back up. Heaphones option was there and audio coming into earbuds. 15" MacBook Pro for me.

Have had the same issue as everyone else on this thread using Yosemite and El Capitan on a late 2011 17" MBP. As its an older model I'd imagine Apple don't care much but I'm surprised that such a widespread and fundamental issue with either their hardware or software was never recognised publicly in forums or support by apple. I imagine its not a software issue as it would be happening on more recent MBPs too if that were the case and then there would really be an outcry!

Going into System Preferences, then clicking on Internal Speakers solved my problem too. I had moved to a new address and my speakers "stopped working". I almost threw my out my relatively new speakers when I learned it would have cost almost the same to buy a new pair. I thought Apple Support would be a long shot, but it worked. Thanks for saving my speakers.

Thanks a lot

it is fantastically easy
