Initially, everything seemed business usual on your Mac. But just when you wanted to stream one of your jukeboxes, a weird issue arrived out of nowhere and stopped the sound from working on the computer. And it’s this problem that has led you to explore the possible solutions to fix Mac sound not working issue. If the scenario sounds familiar, you are at the right troubleshooting guide!
Mac Sound Not Working? Here’s the Fixes
- Turn Down/Up the Volume of Mac
- Free Up the Audio Port and Remove Other USB Devices from macOS
- Remove Debris from Headphone Jack on Mac
- Make Sure the Sound is not Muted in Specific Apps
- Restart Sound Controller on Mac
- Check System Preferences for Sound in macOS
- Reset the PRAM
- Reset the System Management Controller (SMC) of Mac
- Update Your Mac
Solution #1. Turn Down/Up the Volume of Mac
The first trick that I would suggest you try out is to turn down the volume, restart the Mac and then turn up the volume. To do so, use the F11 key to turn down the volume. Then, click on the Apple() logo and choose Restart.
Once your computer has rebooted, use the F12 key to increase the volume. Now, play any song using iTunes or Music app in macOS Catalina. If your Mac’s sound has started to work properly, you are ready to go now.
Solution #2. Free Up the Audio Port and Remove Other USB Devices from macOS
Even after trying the first trick, if the sound is still not working on your macOS device, try to disconnect everything that’s plugged into your computer. Apart from freeing up the audio port, try to get rid of Thunderbolt, HDMI, and USB devices as they could be channeling the audio and preventing it from functioning properly.
Solution #3. Remove Debris from Headphone Jack on Mac
Take a close look at the port to ensure it’s cleaned up and things like dust or dirt aren’t blocking it. Even if your eyes don’t find such culprits, try blowing into it to get rid of the lint that might have piled up over time. Once the port is cleaned up, plug in headphones and play songs. The problem could well be behind you – if debris happened to be the villains.
Solution #4. Make Sure the Sound is Not Muted in Specific Apps on Mac
Just in case your Mac’s sound is working pretty well in the stock music app but not inside other apps like Chrome or Safari, ensure that the sound is not muted. Check out the sound controls inside those apps. If the sound is muted by default, unmute it.
Solution #5. Restart the Sound Controller of Mac
Some users who had run into the “Sound has stopped working on Mac” issue reported that restarting the sound controller helped them in resolving this problem. Therefore, we are going to give this solution a chance as well.
Launch Finder → Applications → Utilities → Activity Monitor and find the ‘coreaudiod’ option. Then click on the Force Quit button (X) at the top left to kill the process manually.
Just in case, you don’t find coreaudiod in the Activity Monitor or feel comfortable using Terminal, you can use a quick command to restart the sound controller with ease. Simply open the Terminal app and type ‘sudo killall coreaudiod’ command. Then, hit the return key and enter your administrator password.
Solution #6. Check System Preferences for Sound in macOS
If the sound of your macOS device hasn’t yet returned to normal, ensure that the sound setting has been configured perfectly. Launch System Preferences app and select the Sound icon. Now, click on the Output tab and select Internal Speakers. Next, make sure the Mute box next to Output Volume is not checked off. Also, keep the Output Volume slider to the right.
- If the Internal Speakers option is missing and Digital Out appears in its place, disconnect everything that is plugged into your Mac. Then, restart your Mac. After that, check out if the Internal Speakers option has appeared
Solution #7. Reset the PRAM
When some of the basic tricks don’t seem to work in troubleshooting the sound-related issues on Mac, I go for resetting the PRAM. And I must say that it hasn’t disappointed me on many occasions. So, give it a go as well.
To do so, restart your Mac. Then, immediately press the Command(⌘), Option (or Alt), P, and R keys at once. Make sure to press those keys until the computer starts and chimes.
Solution #8. Reset System Management Controller (SMC) of Mac
Just like PRAM, SMC (System Management Controller) has also been quite reliable in fixing persistent issues on Mac. So, it would be wise to give SMC a fresh start as well. Do note that the process varies based on the kind of Macs.
On the MacBooks with Non-Removable Batteries
- Turn down the notebook and unplug the power cord. Then, press and hold down the Shift, Ctrl and Option (Alt) keys, and the power button simultaneously
- Make sure to press these keys for 10 seconds. After that, release the keys and the power button at once
- After that, press the power button to turn on the notebook
Older MacBooks with Removable Batteries
Shut down your MacBook and unplug the power cord. Now, remove the battery from the notebook. Then, you need to press and hold the power button for up to 5 seconds. After that, fit the battery back in at its normal place. Next, plug in the cord and turn on your notebook.
Turn down the desktop Mac and then unplug the power cord. Now, wait for 15 seconds and then plug in the power cord. Next, wait for five seconds and then press the power button to turn on the computer.
Solution #9. Update Your Mac
Believe it or not, software update always proves quite handy in fixing common problems like self-assigned IP address and iPhone is not showing up in Finder. So, the answer to this issue might also be packed inside the latest macOS update, if the problem is caused by a bug. Click on Apple() menu → System Preferences → Software Update. Now, update your Mac to the latest macOS version.
Hopefully, the sound of your Mac has returned to normal. But before you go on to stream your favorite flicks or shows, share with us the tricks that got the job done for you. Just in case, things haven’t returned to normal as yet, I would recommend you to contact Apple as there could be hardware issues.
