Determine The Causes Of Mac Sound Not Working

Sometimes this no sound problem happens because you have your Bluetooth on and it sends the audio to the device your computer is connected to. A simple restart can fix many minor issues our computer is having, including audio problems. After the restart, you can check again and see if you get the sound back. This may well help solve sound-related problems. This reboot will take up to 20 seconds. In this method, we create a new Apple account and test if sound works properly in this new account.

Then enter the user password if asked. Tap the volume up F12 key to turn up the sound level. You should also check other sound sources, like iTunes and QuickTime movies to find out if they can play sound. Click Autoplay, and in the bottom right of the window, choose Stop Media with Sound. The window that opens will have the name of the version of macOS currently installed at the top. Now the latest version is macOS High Sierra. To check that, click Software Update in the About this Mac window.

If there is, install it. Before you install either a new version of the OS or an update, backup your Mac using Time Machine , or whichever backup tool you normally use. These optimize the performance of your Mac by running a number of routines such as repairing disk permissions, verifying your startup disk, and rebuilding the launch services database. The best thing to do in that instance is to uninstall the app. To do that, you should use a dedicated uninstaller like CleanMyMac X.

You can download CleanMyMac for free here. The most common occurrence of this problem is on pre Macs that had a digital audio output support in the headphone jack. On those Macs, there was a sensor in the port that detected whether a headphone jack or a digital audio device was plugged in.

The Mac would then change the output to headphones or digital output accordingly. Didn't work for me. It switched to digital output. But still has red jack and muted sound.

The above didn't work for me, nor restarting. The red light went out and "Internal Speakers" appeared in the list where it should be. Try it with or without the headphones plugged in, whichever works. Another thank you to go on the list.

Audio & Sound Not Working in Mac OS X? It’s an Easy Fix

So grateful; like others I had to try it twice, but very relieved. Good to read alternative options in comments too. Best wishes from Lisbon, Portugal. Joe here, blog owner. For what it's worth, the procedure I've outlined above doesn't always work for some reason.

  • If you've read this far, I'd suggest trying IT2's solution from a few lines up. I was going bonkers but it worked. Sending a happy hug. Can you handle another expression of gratitude? Have had the problem in the past, didn't remember what I'd done to remedy, tried this and it didn't work and second time it did. Thanks much for sharing! Woo Hoo! Took a few times. Like others, I missed the part about turning off the sound.

    Finally worked with IT2's solution. With headphones in, hit mute on and off, pulled out the headphones and I have speakers again! Just had this exact thing happen. Did a quick google search and came across your site. The fix worked exactly as you described Joe. This didn't work for me. I unplugged the headphones and it set itself back to optical.

    No sound after upgrading to macOS Mojave — here’s your fix

    IT2's solution did not work either. I just fixed the problem, after none of the above worked, by just plugging in and unplugging the headphones like 15 times. If I pull out headphones, yes, it changes to digital out, but then the icon greys out again and I am once again unable to alter the sound levels. However, I am please that I can at least use headphones or speakers cuz I am currently deep in a rustic cabin deep in the rainforest and my laptop is my sole amusement once the sun goes down.

    I will try someone else's suggestion of plugging and unplugging the external speakers fifteen times next as that was what was last plugged in.

    Thanks so much for putting this up. I would have never been able to work that out! Thanks again. None of these worked for me, but eventually I jammed a plastic tube the inside of a pen into the socket and rotated counterclockwise. After a few tries it worked! Definitely a stuck switch. Saddly, It didn't work! Help me! This has been annoying me for a few days now and with your advice, YOU fixed it for me in less than a minute!

    • Now I can play my music. Thank you for your excellent help!!!! I am so happy! Fiddled with it for ages! And the only way I could find this was by print screening the mute sign and using google image search! A fix: after a lot of fiddling with no success, I discovered that when I plugged into the sound output with headphones and changed my sound settings to use audio port for sound INPUT, the internal speakers kick in.

      Had an old set of bad headphones, cut off the jack, and used that jack plugged in, with the INPUT setting, and get speakers to work. Or buy a jack at Radio Shack for a few bucks if you have no defective phones laying around? Good luck! I had to try a couple of different times, paused the music, then unplugged the headphones, but it did finally work! Thanks so much! I followed the rules and it didn't work. I did a slight variation in that whilst the song was playing in i-tunes i pulled the headphones out and it then started to play through my internal speakers again! I am happy camper once again!

      Thank you SO much. So helpful. I spent 10 minutes sticking toothpicks in my headphone jack.
