How to Fix a Mac device’s speakers crackling?

Here are some quick tips on how to fix this issue:

Restart your Mac device

Yes, let’s first restart your device. Click on the Apple icon on the top left corner of your screen and click restart.

Clean out your speaker holes

One of the most common reasons for a speaker crackling on a Mac is simply due to dust and debris accumulating in the speaker holes. Over time, this can cause audio quality to degrade and even eventually lead to physical damage to the speakers themselves. To clean out your speaker ports, simply use a can of compressed air to blast away any dirt or grime that may have built up. If you don’t have access to compressed air, a cotton swab or toothpick can also do the trick. Just be careful not to insert anything too far into the hole and damage the speaker itself.

Update your software

Another possible reason for the speaker crackling on your Mac could be outdated software. Keeping your software up-to-date is important for many reasons, but in this case, it can help prevent audio issues like crackling from occurring. To check for updates, open up the App Store on your Mac and click on the “Updates” tab at the top of the screen. If any updates are available for your installed apps, click “Update All” to install them. Once the process is finished, restart your computer and see if the issue has been resolved.

If you’re still hearing crackling from your speakers after trying this method, move on below.

Check Audio Output Settings

Check to make sure that the audio output settings on your computer are set to “internal speakers.” To do this, go to System Preferences > Sound > Output. If you see that the Output is set to “Bluetooth” or “Headphones,” change it to “Internal Speakers.”

If you don’t see “Internal Speakers” as an option, make sure that your computer’s volume is turned up by clicking on the volume icon in the menu bar and dragging the slider to the right. You should also check to see if there is something plugged into the headphone jack; if there is, unplug it.

If changing the Output setting and/or increasing the volume doesn’t solve the problem, try restarting your computer again.

Reset PRAM

If restarting doesn’t work, try resetting your computer’s PRAM. PRAM stands for parameter random-access memory and resetting it can often fix issues with sound output. To reset your PRAM, follow these steps:

1. Shut down your computer.

2. Turn it back on and immediately press and hold these four keys together: Option, Command, P, and R. You can let go of the keys after about 20 seconds, during which time you should hear a startup sound (if not, try again from step 1).

3. If you hear two startup chimes in a row instead of just one, that means that PRAM has been reset successfully.

4. Afterward, open System Preferences > Sound > Output and make sure that “Internal Speakers” is selected as your Output device.

5. Finally, try restarting your computer again.

Try a different set of speakers

Try a different set of speakers  If none of the methods above have worked to fix the speaker crackling on your Mac, there may be an issue with the speakers themselves rather than with the computer itself. To test this hypothesis, try connecting a different set of powered speakers or headphones directly to your Mac’s headphone jack or Thunderbolt port (if available).

Following these steps should fix most speaker crackling issues on Mac computers.
