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.

Hey! I had the same issue. I think I've managed to fix it by making sure that my MIDI output is set to 48.000 Hz. Go to Audio MIDI Setup settings, under Macbook Pro Speakers set the output to 48.000 Hz if its anything else (like 44). You might have a software installed that has changed the Hz value (and possibly some other under-the-hood sound settings as well). So far it has fixed the issue to set it back. I have not yet updated to Mojave, but has installed all updates up until that. See picture below.

"MacBook Pro has beautifully balanced, high‑fidelity sound that takes listening to new levels with wide dynamic range and more bass for maximum boom. And the speakers are connected directly to system power, enabling greater peak amplification. So you can mix a track on the fly, edit video on location, or enjoy a movie on the go."



Didn't know cracking sounds were part of the deal.....

I'm also get the crackling sound using YouTube and the repeating effects. Also on Facebook and my Ableton Live. I called Apple Support and they had me reset my SMC settings which helped for 20 minutes and now I back to crackling. I just replaced my previous 2018 15" Macbook Pro because it was having flickering screen and slow track pad issues. Now crackling sound. Not good luck for me. Might have to return it again. Hoping it's just a software update issue. Really disappointed with the new Macbook Pro bugs/issues.

I haven’t had a chance to read all the replies so this might have already been said but on my 15” 2018 MBP whenever I am watching a video on YouTube or other websites the audio cuts out randomly for a couple of seconds. I thought it might be something to do with my internet which can be unreliable at points but I noticed whenever it happened the mute button on the Touch Bar would light up as if it were pressed and then turn its self off again a second or so later? Could this be a software bug?
