Hold these down and power on your machine.

Locate the 'Command' button and the 'R' button. Once completed, shut down your computer.ģ. Note that my sound issue did exist at the time of backup, don't worry about that.Ģ. This may take some time but stick with it. First of all backup your Mac to an external drive using Time Machine. I'm hoping my post might help some desperate people out there who want their sound back! Huuuge thanks to this YouTuber: ġ. Sorry to resurrect an old post, but I searched for a whole week for a solution and spoke with 3 separate Apple consultants who just repeated the same 'solution' (reinstall OS X which didn't work for me). If a jack or swab doesn't work, I've heard of people successfully resetting it with a deft poke of a toothpick. Rather, it may be that the switch just needs a subtle nudge. It's possible that gunk has nothing to do with it. (This same technique works well with misbehaving headphone ports on devices such as iOS devices.)

I recommend foam rather than cotton swabs because the cotton variety might leave threads behind. If that doesn’t work, find a foam-tipped swab that fits (electronics shops generally carry them), dip it in rubbing alcohol, and gently insert it into the headphone port in an attempt to wipe away any stubborn gunk. With any luck, that should dislodge the gunk and the port will operate as it should. Before turning to more invasive techniques, get a can of compressed air, attach the small tube that fits the nozzle, and blast a few shots of air into the port. If that doesn’t work, there may be gunk in the port. Much of the time, this takes care of the problem by correctly tripping the sensor. The safest way to do that is to simply run a jack in and out of the port a few times. The solution is to force the sensor to do its job.

That’s why you see Digital Out instead of internal Speakers. When you removed the jack, something in the port prevented the sensor from tripping correctly. The spirits tell me that there’s a very good chance that you recently had something jacked into this port-a set of headphones or a cable leading to powered speakers, for example. When you remove the jack completely, it should read Internal Speakers. If you insert a jack for digital audio output, the device changes to Digital Out. When you insert a headphone jack, the sensor understands what's what and changes the sound output setting to Headphones. The background on the issue is that there’s a small sensor switch inside the headphone port. Trick/Tip: Open up GarageBand if installed then, open a program (optional).
