Whether it's static noise or no sound, it's never a good surprise when your computer gives you the silent treatment after you plug in your headphones. A broken Mac® audio jack can be frustrating, especially when it interrupts your flow of music or video calls. Don’t worry—we’ve got you covered.
At uBreakiFix® by Asurion, we have the tech know-how to tackle any device problem, from slow startups to system crashes. Here’s what our team has to say about fixing a headphone jack that’s not working on a Mac.
Why the headphone jack isn’t working on your Mac
There are a few reasons why your headphone jack might not function as expected. It could be something as simple as the system settings diverting audio elsewhere or a more complex hardware issue. We’ll start with common culprits, like dirt accumulation in the jack or software settings, before moving to more involved fixes.
How to fix a broken Mac headphone jack
Here are some ways to resolve your malfunctioning audio jack problem.
Try another pair of headphones
Before diving deeper into technical fixes, it's a good idea to eliminate the simplest cause: the headphones themselves. Connect a different pair of headphones to your Mac to determine if the issue is with the original pair or the audio jack. This quick test can save you time and potential troubleshooting if it turns out that the headphones were the problem all along.
Clean the headphone jack
Dust and debris in your computer’s audio jack can prevent it from working properly. A quick clean can often restore clear and uninterrupted audio.
Verify the audio output settings
Start by checking your sound settings to see whether the audio is connected to your headphones. Click the Apple Menu, select System Settings > Sound > Output, and make sure your headphones are the selected sound output method.
Restart your Mac
Sometimes, a simple restart can clear up any temporary glitches with your headphone jack. Click the Apple menu in the top-left corner of your screen, then select Restart. After your Mac restarts, try the headphones again.
