My MacBook Pro 2018 version speakers are crackling.

Apple informed some macrumors users that an update is in the way

The latest update (available in the App Store) fixed my audio issues.

Since it still new you able request for replecement.

Since you just got it replaced you could wait at least until the return period is almost over. I believe this to be a softaware problem and not a hardware one.

I’m currently in contact with one of Apple’s Help Desk operators. And they titled it “T2 tech: Audio is chuncky”! lol

So, it’s most likely, as everyone is guessing, related to the T2-chip.

I've found that I don't have to fully restart the app, just ctrl+tab or cmnd+tab (depending on OS) to leave the app and stop the sound for a second. I think it's an issue with continuous speaker usage so that pause fixes it (only temporarily ofc)

Edit: I've only noticed this problem while in Windows Bootcamp, macOS is perfect for me

You know the sad thing is they are actually saying they havent heard about this issue. The told me that it was my time machine back up which was the issue. but you know They gave me a new laptop on wednesday and on thursday it started crackling again so i decide to back up my back , wipe it to factory settings and then try and see if i could hear anything and sadly i haven't heard anything yet which makes me wonder what the **** i am going to say to the Apple tech when i see him.

OKAY so i just got back form the apple store where i had an appointment with the Apple Genius bar technician. Now i have had this issue for awhile , got a replacement laptop and basically because its a problem that only happens every now and then i will let you all now that when i went in i couldn't prove the sound BUT the technician said to be that were many forums and people saying that they were having this issue BUT because apple havent released a statement about it yet nothing can be done. They are still trying to tell me that it could be my time machine back up and they told me that i must try an restart my laptop as a new one and i said thats absolute rubbish that i pay this amount to loose my data and start from scratch. ANYWAYS his opinion one what i should do is "wait it out"

FYI, Same issue on my new Macbook Pro, and the music playback got out of sequence during the cracking. Unplug and plug back in headphone helps, until the issue comes back later.

It happens to both the internal speaker (aka MacBook Pro Speaker) and headphone, so it is unlikely speaker issue.

It’s not a hardware issue. It’s down to software. I’ve been using my mb pro 2018 for the last month and there’s only ever a problem with sound when I’m using blender and even then it’s very infrequent which suggests it’s a software bug. Once I close blender the problem goes away and I’ve been playing music and steaming off YouTube with no problems for hours on end.

Hopefully it will be fixed once Mojave is released.

Hello from Russia! The same problem with the official MacBook Pro 15" 2018, 2.6 GHZ, 560X, which I purchased from the official Apple reseller in Russia three days ago. I don't work with Bootcamp or logic Pro. But I have Adobe Premiere pro 2018, and this problem appeared in it.
After about 40 minutes of work in Adobe Premiere speakers start to rattle, the sound starts to lag and repeat. If you immediately restart the Premiere, the problem disappears for some time and does not apply to the entire system. But if you work with this problem for another 10-15 minutes, the problem begins to manifest itself in other conventional programs, where there is sound, in the browser, in YouTube, in a music or video player on the computer. And then it helps only to restart the computer.

Called in Russian support of Apple, there is about this issue heard and know, but officially can't say for sure, because the authorities in America is silent. Offer to carry a computer in service, to make the diagnosis and to look for technical solution. And this is three days after buying a brand new device!

Before that, 5 years used MacBook Pro 15, late 2013, and there were no such problems at all.

I read all the messages from this branch and decided not to carry the computer to the service yet, try to use the options that are offered here. Or wait for a new operating system, suddenly everything will be repaired.

In general, not only in your countries the problem with this model of MacBook Pro... And this very strange!

Still have the issue on bootcamp even after the second supplemental update did take a little longer but still crackles badly in a game. Went to the apple store which they said that only an update can fix it as its a software issue/driver issue so I need to await an update for bootcamp.

It's fixed (and I haven't heard a cracking sound other than one short suspicious sound on starting first playback, after system reboot), but @timcook and his fellows have to show courtesy on facing issues:

Daniel please contact Official Apple Support and tell them!

It's of no use if you come on this support forum without mentioning to Apple Support because they do not look at this.

And if you contact them they can escalate it to the appropriate team and at least let the engineers know!!

Please do it as soon as you wish. It will benefit not only you but the others too.

I had to change my MBP 2018 3 times and finally got one without crackling issues and popping issues.

To be clear, there are two separate issues - 1) a random popping sound due to the display panel not being manufactured properly and 2) a speaker crackling issue that probably is software based.
