Why Are You Facing MacBook Audio Issues?
First, let’s figure out what’s causing MacBook audio issues. Pinpointing the root of the problem can make solving it a lot easier.
- Output Settings Gone Wrong: Your MacBook might be trying to send sound to the wrong device—like a Bluetooth speaker you’re not using.
- Software Glitches: A buggy app or macOS update can mess with your audio, leading to MacBook sound problems.
- Hardware Issues: If the speakers are damaged or there’s a loose connection, you might hear a MacBook crackling sound.
- Background Apps: Sometimes, an app might “steal” the audio output, causing MacBook no sound issues.
Understanding these causes can help you tackle MacBook audio issues more effectively.
How to Fix MacBook Audio Issues Like No Sound or Crackling
Check Your Sound Output Settings
One of the most common reasons for MacBook no sound is that the audio is being sent to the wrong place. Let’s make sure your MacBook is outputting sound where you want it.
- How to Do It:
- Click the Apple menu > System Settings > Sound.
- Under the “Output” tab, make sure “Internal Speakers” (or your preferred device) is selected.
- If you see a Bluetooth device or external speakers selected, switch back to your MacBook’s speakers.
This quick check often resolves MacBook sound problems in seconds. If you’re still having trouble with the output settings or want more detailed steps, Apple’s official guide on troubleshooting sound issues with Mac speakers can walk you through additional checks to ensure your audio setup is correct.
Restart and Test the Audio
Sometimes, MacBook audio issues are just a temporary glitch. A simple restart can get things back on track and fix issues like MacBook crackling sound.
- How to Do It:
- Save your work, then restart your MacBook by going to Apple menu > Restart.
- Once it’s back on, play some audio—like a song or a YouTube video—to test if the sound is working.
- If you’re still hearing a MacBook crackling sound, try adjusting the volume to see if it changes.

This basic step can clear up minor MacBook sound problems without much fuss.
Update macOS to Fix Software Bugs
A lot of MacBook audio issues stem from software bugs, especially after a recent update. Keeping macOS up to date can resolve MacBook no sound or crackling issues caused by glitches.
- How to Do It:
- Go to System Settings > General > Software Update.
-
If an update is available, download and install it, then restart your MacBook. Want to know which updates are worth your time? Take a look at our article on Top macOS Updates You Shouldn’t Skip in 2025 for the latest on macOS improvements

Updates often include fixes for MacBook sound problems, so don’t skip this step.
Reset the Core Audio Process
If you’re still facing MacBook audio issues, the Core Audio process (which handles sound on macOS) might be stuck. Restarting it can help with issues like MacBook crackling sound.
- How to Do It:
- Open Activity Monitor (search for it using Spotlight).
- In the search bar, type “coreaudiod” and find the process.
- Select it, click the “X” button to quit it, and macOS will automatically restart the process.
- Test your audio again to see if the crackling or no-sound issue is gone.
This trick often clears up stubborn MacBook sound problems without needing a full restart.
Check for Hardware Issues
If none of the above fixes your MacBook audio issues, the problem might be hardware-related—especially if you’re hearing a persistent MacBook crackling sound.
- How to Do It:
- Plug in a pair of headphones or external speakers to test if the issue is with the MacBook’s internal speakers.
- If the sound works fine through headphones but not the speakers, the internal speakers might be damaged.
- In this case, it’s best to take your MacBook to an Apple Store or authorized repair center for a closer look. For more tips on diagnosing hardware problems, see our guide on How to Troubleshoot Common MacBook Hardware Issues to better understand what might be going wrong
Hardware issues are less common, but they can cause MacBook no sound or crackling problems.
Tips to Prevent MacBook Audio Issues in the Future
Once you’ve fixed your MacBook audio issues, a few habits can help keep your sound working smoothly:
- Keep macOS Updated: Regular updates can prevent MacBook sound problems caused by software bugs.
- Avoid Overloading Apps: Too many audio apps running at once can lead to conflicts, so quit apps you’re not using, don’t just minimize them.
