Question: My MacBook Pro 2018 version speakers are crackling.

Hello. A few days ago I got the new MacBook Pro 2018 15in version. I’ve noticed since yesterday that my MacBook Pro speakers were crackling randomly. I’m not sure if since this is a new release that there are bugs in the software or if it’s an actual defect. Because before yesterday, I haven’t experienced this issue. I resetted the NVRAM and did a diagnostics test with no issues. After about 10 minutes of use that’s when it does it. Then stops. I think I might hopefully but not hopefully have to get it replaced since it’s under the warranty still. I did nothing to it. So this is dissapointing to me.

You are not the only one with this issue. There's currently a thread at MacRumors MacBook Pro 2018 - Speakers Crackling | MacRumors Forums with a lot of people with the new Macbook 2018 and the same problems.


It happens on both MacOs and Bootcamp. Restarting the application or game often solves it, but as it happens within 10 minutes of starting a game, restarting it each time is just no option. There are people that have brought back their MBP and got a replacement but those had the same problems.


So it seems like it is a real issue, let's just hope that they can fix it through software.

Hello and welcome to Apple Support Communities, IdentifiedGamer!

I understand you've noticed crackling in your speakers recently, that does not happen consistently. I'd be happy to provide information that may help you resolve this issue.

Have a look at this article: Get help if the internal speakers on your Mac don't make sound

Check your sound settings

If you still can't hear sound from the internal speakers after updating your computer's software, check your sound settings.

First, disconnect any external audio devices from your computer. Also disconnect any cables from the USB, FireWire, or 3.5mm audio ports.

  1. From the Apple () menu, choose System Preferences.
  2. Select Sound.
  3. Click the Output tab, then select Internal Speakers. If you don’t see Internal Speakers as an option in the Output window, contact Apple Support.
  4. If the volume slider is set low, move the slider to the right and test again.
  5. If the Mute checkbox is selected, deselect it and test again.
  6. If you still don’t hear any sound, contact Apple Support.

Check the line-out port on your Mac

If the Output pane lists Digital Out instead of Internal Speakers, check the line-out port on your Mac.

First, disconnect any external audio devices from your Mac. Also remove any cables from the USB, FireWire, or 3.5 mm audio ports. Then check to see if the line-out port is lit by a red light. If it is, your Mac might need service.


If the issue persists, please reach out to Apple Support for further assistance.

Thank you for using Apple Support Communities.
Have a great day!

I have a problem with mine as well! I got the 15" i9 version and it was very annoying how the sound would randomly cut-off with no obvious reason, went to the apple store got it replaced but still the same issue persists on the new one as well! (not as frequent though)
I'm currently in touch with Apple support and they have the sysdiagnose for both MacBooks and I'm just waiting for apple engineers to figure out exactly what is going on!!

I think I’m gonna have to get this thing checked out. I was watching a YouTube video and the audio was repeating, even when the video was paused. So I’m gonna hope I can head to the Apple Store to get it checked out.

This is probably a problem with the T2 co-processor as some news were quoting these had some other problems and they also control the sound. I have the same problem on my iMac Pro... sound cracking, doesn't matter if I'm using external or internal speakers, it happens on both so it has to be a chip issue. Just to clarify there are two scenarios: 1) Sometimes it is just momentary "one-off" crack or pop and then sound goes back to normal. 2) The sounds cracks and keeps cracking until the output is changed. Changing from one output to another momentarily resets the problem though, but doesn't prevent it from appearing again later.
