As I read this query posted by a concerned Mac user, I realized that the MacBook sound not working is such a common issue. The good news is that mostly the Macbook no sound issue is caused by some minor problems that can easily be fixed. Whenever my MacBook has no sound, there is a series of troubleshooting steps that I take. In this post, I will let you know all these tried-and-tested solutions to fix issues like MacBook Pro no sound on your own!
Before I get into the details and start the troubleshooting guide, let's discuss some of the common reasons causing the MacBook no sound issue. In this way, it would be easier for you to identify the problem and fix it quickly.
If there is no sound coming out of the MacBook, then the issue can be triggered due to different reasons. I would recommend the following solutions to fix the MacBook Pro/Air with no sound problem.
Before you take any drastic measures to reset sound on Mac, make sure that all the other vital components are working.
Chances are that you would have made some changes in the sound settings on your Mac unintentionally. To fix the MacBook not playing sound because of that, I would recommend this fix.
Step 1. Firstly, go to the Finder and browser to System Preferences > Sound.
Step 2. As the Sound settings would be loaded, go to the "Output" tab and make sure the default output is for its internal speakers (or any other preferred source).
Step 3. Additionally, you should check that the output speakers should not be muted from here. You can also adjust the output volume of the speakers to ensure it is audible.
Sound Controller is the core component in Mac that is responsible for playing audio files correctly on it. If the Sound Controller has not been booted or working properly, then you can have no volume on Macbook. To fix the MacBook audio not working issue, you can consider restarting its Sound Controller.
Step 1. Just go to your Mac's Finder, browse to Applications > Utilities and open the Activity Monitor.
Step 2. Once the Activity Monitor window is launched, search for the "CoreAudio" process.
Step 3. After finding the Core Audio component, select it, and click on the cross icon to close it.
Now, wait for a while, close the Activity Monitor, and try playing a sound to restart the Audio Controller.
If you are able to get sound on your Mac's internal speakers, but the connected Bluetooth audio is not working, then you can try this fix. Beforehand, just make sure that the overall sounds on your Mac are working and that the Bluetooth device is also functioning.
Step 1. Go to your Mac's Finder and browse to System Preferences to launch the Bluetooth settings.
Step 2. Once the Bluetooth window is launched, just select the connected device and remove it from here. If you want, you can turn off Bluetooth from here entirely, wait for a while, and turn it on again.
Step 3. Afterward, you can try to pair your Bluetooth device with your Mac from here as well.
Step 4. If it still won't work, then click on the Bluetooth icon from the Finder and go to its Debug > Factory Reset all connected Apple Devices option.
Step 5. Follow a simple click-through process to reset the connected devices and your Bluetooth settings.
As stated above, chances are that the essential components in your Mac might not have initiated properly. If there is any firmware-related issue causing the MacBook Pro no sound problem, then consider resetting its PRAM. This is a non-volatile RAM that stores information about its booting and connected devices.
To reset your Mac's PRAM, just restart your system and press the Command + Option + P + R keys at the same time. You would have to hold them for a while and let go once you hear the second chime while booting. Now, wait as your Mac would be restarted and check if it fixes the MacBook sound no working issue.
Apart from the MacBook not playing sound error, chances are that you might encounter similar issues while playing a video. In this case, I would recommend the following suggestions to fix MacBook Air's no audio problem while playing videos.
If you think that your video file has no audio component, audio sync issues, or the media has been corrupted, then consider using Wondershare Video Repair. It is a sophisticated video repairing application that can fix all kinds of playback errors in your media file. You can perform its standard scan by loading multiple videos at the same time. If you want, you can also perform an advanced scan that might take more time, but will also yield better results. Here's how you can fix no audio issues in a corrupt video file using Wondershare Video Repair.
Step 1: Add the videos to repair
At first, just launch Wondershare Video Repair on your system and add any corrupt video to the interface. You can click on the add button to browse the file or just drag-and-drop it here.
After when the videos are added, you can view their details on the interface. You can add/delete any video from here and click on the "Repair" button when you are ready.
Step 2: Preview and save the repaired videos
Once you start the repairing process, the application will automatically fix the loaded videos in no time. In the end, you can preview the results on its interface and click on the "Save" button to restore the video.
Step 3: Perform an advanced video repair (optional)
If your files are extensively damaged and the standard process is not able to fix them, then you can click on the "Advanced Video Repair" option instead. This will ask you to load a sample video for the corrupted file that would be kept as its reference. The sample video should be of the same format and shot on the same device as the corrupt one.
Similarly, you can start the repairing process, preview the results in the end, and save your video. The application will let you browse and save your repaired videos to the location of your choice.
You can get the MacBook Pro audio not working issue while playing a video with an unsupported media player. It might happen that the format of the video file that you are trying to play is not compatible with the application. Alternatively, there can be something wrong with the media player as well. You can just go to the App Store on your Mac and download a reliable video player that would support its format.
It might surprise you, but when I encountered no sound on my MacBook, I was able to fix it by updating it. Needless to say, if the media player or the firmware hasn't been updated for a while, then it can cause tons of unwanted problems.
If you use iTunes, then you can just launch it on your Mac and go to its main Menu > iTunes > Check for Updates. This will launch a dedicated wizard that will let you update your iTunes to the latest stable version.
Also, you should try to update your Mac to its latest macOS version as well. For this, go to its Finder > System Preferences > Software Update and check the latest available update from here. After that, restart your Mac, and check if the macOS sound not working problem sustains or not.
There are times when users only encounter no volume on MacBook Pro while playing audio on a web browser. Since this can be a specific issue, I would recommend these fixes for the MacBook sound not working in browsers.
It doesn't matter if you are using Safari or Chrome on your Mac, the presence of some unwanted extensions can cause MacBook no sound in browsers. To do that, you can just go to the browser's extensions by its URL or from its Settings. Review the installed extensions and deleted any unwanted extension that you think can cause issues with your Mac.
When was the last time you cleared the cache and another browsing history on Safari or Chrome? If it has been a while, then the accumulated data can make your browser slow and even cause Mac's sound output not working problem. You can go to your Chrome's Settings > Privacy > Browsing Data to do that. From here, you can choose to delete its browsing history, cache, log files, and more.
Similarly, if you use Safari on your Mac, then you can go to its Menu > Safari > Preferences > Privacy. Now, click on the "Remove all Website Data" feature and get rid of all the unwanted files from your Mac.
Although the Hardware Acceleration feature is meant to speed-up your browsing experience, it can sometimes cause conflict in the system. The best way to fix the MacBook no sound issue in browsers is by just disabling the feature. The option can be located in different sections on your browsers. For instance, Firefox users can find it under Settings > Advanced while Safari users can find it under System Preferences. Once you locate it, just disable the feature and restart your browser.
By now, you would know what to do if MacBook won't play sound anymore. Though, if you don't want to encounter this issue ahead, then consider these tips.
