The MacBook Pro is an amazing laptop that makes productivity tasks like writing, photo editing, graphic design, video editing or checking emails easy.  But if you want to kick back with a show or listen to some jams, you need the sound on your MacBook to work the way it’s supposed to.

If your MacBook Pro isn’t playing sound, we have a few tricks that might work for you. Give these a try before you rush off to get a new set of speakers! 

What To Do When Sound Is Not Working On MacBook Pro

Start with the basics. Try these tips before you rush off to the Genius bar for a pricy fix.

Volume Up

Shocking, I know– but most of the time, our laptops are only silent because we told them to be. Make sure the sound on both the application you’re using and the MacBook Pro you’re on is turned up properly. It would be a shame if you took it all the way to a repair shop only to find the fix was that easy!

Plug Headphones In 

If that doesn’t work, try this step next: plug your earphones in to the laptop and see if the problem persists. You may find that you’re able to enjoy sound through your headphones, though your speakers still don’t work.Sometimes an error with the headphone jack can cause the laptop to read as though a headset is plugged in, even when there’s nothing there. Software issues can lead to similar problems. In some cases, simply plugging your headphones in and then unplugging them could resolve the issue altogether!

Try a Different App

The sound issue may be particular to the application you’re using. Try another application to ensure the sound problem is actually with your device, and not with the app.

For instance, if you are watching a movie from a streaming site and the sound isn’t working, you can check iTunes or YouTube to see if the problem will continue.

Restart Your MacBook Pro

Restarting your MacBook will fix all kinds of issues, including ones involving sound. So, if your MacBook Pro’s sound still isn’t working, give it a quick reset.

To restart your MacBook, click on the Apple logo on the screen’s left corner and select restart. It’s a simple process. Once it’s ready, open the same app and play your movie or music again. By this time, it should be working.

Ensure There Aren’t Hardware Issues

There are instances when sound is not working on your MacBook Pro because there’s something plugged into the headphone/lineout port.

So, check to know if there’s a red light on the port. If it’s there, it means that the port is either faulty or something is blocking it. Whichever be the case, try to clean dust and other tiny debris from the port to see if it will work.

See If You’re Running the Latest Mac OS

If you are not running the latest Mac Operating System, it may affect a couple of functions; including the sound system. So, check if your OS is up to date. If not, consider updating the latest version.

Click on the Apple Menu and About this Mac. A new window with the version of operating system your MacBook Pro is using will open. If you are running an outdated OS, go to the app store to get the most recent version.

As a rule, ensure that you backup your Mac before installing a new version or Update the existing Operating system.

Check Sound Settings

There are instances when your MacBook Pro sound not working is due to settings. So, you can check the sound settings to ensure that you aren’t leaving anything to chance.

Start by removing all external audio devices, like wireless earphones and external speakers. Once you have done this, follow the steps below to check the sound settings;

– Click on Apple Logo on the Top left corner of your screen

– Select system preference

– Find and click “Sound”

– Click the “Output” tab on the sound window

– Click the internal “Speakers”

– If the mute box is ticked, uncheck it

– Move the slider to the right to increase the volume

– Close the window and see if the sound is working

Sometimes, you may see digital out instead of internal speaker, it’s an indication that external devices are connected to your MacBook. What you should do is to disconnect all external devices and check the list again.

Reset NVRAM or PRAM

NVRAM is an acronym for Non Volatile Random Access Memory while PRAM Stands for Parameter RAM. NVRAM keeps information relating to your MacBook Pro sound volume, startup disc selection, display resolution etc.

So, if you reset NVRAM or PRAM, MacBook pro sound issues may be restored. Here’s how to reset both NVRAM and PRAM.

#1. Power off Your Mac

#2. Once you turn it back on, press the option, command, P, and R keys all together at a time.

#3. Once you hear the start-up chime, release all the keys. Great! You just successfully reset your NVRAM and PRAM.

Restart the Sound Controller

If your MacBook Pro sound is still not working after exhausting all the options mentioned above, you should restart the sound controller. It involves launching Activity Monitor, but it’s a simple process. I will guide you through it.

– Navigate to the Application Icon, Click on Utility and double-click on Activity Monitor to launch it.

– Type ‘coreaudiod’ in the search bar to locate the Core Audio controller.

– The next step is to click on coreaudiod. After which, you should click on ‘X’ in the toolbar to quit. 

– Core audio will then restart.

Conclusion

But if none of the suggestions above work for you, it’s best to leave your fix to the pros. They should be able to detect the problem with your sound system.
