My MacBook Pro 2018 version speakers are crackling.

I have not used nor have any of these audio programs. My 2018 15" MBP (not even 2 weeks old) has only been used for and at work so far, running nothing but browsers (happens on both Safari and Chrome) watching YouTube or Playstation Vue, iTunes, iMovie, and Adobe Dreamweaver, Illustrator, and Photoshop. I also use a pair of bluetooth earbuds, which I can and have listened to for hours without any issue at all. It's only ever using the built-in speakers.

After reading several forums, and seeing people having no luck at all with replacing them, I just don't have the confidence that swapping it for a new one will fix the issue, and I really don't think it should have to resort to that when there are so many people experiencing the same exact problem.

Hey there, I know I’m late in the game, but I bought my new MacBook Pro 15” 2018 around the same time you did, and have been experiencing the same problem. Many times a YouTube video or Logic Pro X will just lock up and begin to loop some sound fragment over and over again. Also locking up the functionality of the computer, forcing a hard restart. After Mojave was released, it got better, but I’m still getting the random repeating sounds and crackling pops from the speakers regardless of the application. Having bought the computer for music production, I’m hoping a resolution is discovered regarding this. I’ll report anything I find after my next discussion with support.

I have exactly the same issue while something is playing through built-in speakers, although it has never occurred while I was using Bluetooth headphones.

It might be a hardware issue overall. So not a problem with the actual speakers but how the hardware functions as a whole.

@ios-dev-human I have the i7 Version, also don't worry its the same across all variants as long as its the 2018 Model we all have the issue present.

so, what's their explanation and potential solution on this?

Disabling audio related seems to fix things temporarily but it returns after a while in most cases.

Yes, definitely meant the latest update from the 29th (yesterday for me in Australia). Hopefully it can fix what we've all seemed to have been plagued with. 🙂

You could try clean install mojave in other MBP. Don't install the beta version.

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!!

That's the problem I have, netflix and youtube are gonna stop for a second or two, cut the audio then start again, with quicktime it's even worst, it's gonna stop the video completely, and keep cutting the audio for the next 2 seconds...
