My MacBook Pro 2018 version speakers are crackling.

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.

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.

Did you ever get this resolved? I'm experiencing the same on iMac Pro.

Same issue. You can fix it temporarily in terminal by issuing a sudo killall coreaudiod. The problem usually returns within 20 minutes to an hour for me. Extremely frustrating when working in Logic Pro.

I have the same or similar problem. After about 50-60 minutes of audio playback or usage in iTunes, YouTube, and Logic Pro, etc., the computer starts to make a low distorted tone every 5-8 seconds. This nasty "bonk" tone oscillates a bit, but it sounds absolutely terrible. It sounds like it may be some kind of internal clocking issue, but I have no idea and neither did the guys just now at the APPLE STORE. Putting the computer to sleep or restarting alleviates the problem, but it then returns on schedule. Apple Store suggested reinstalling OS, but I don't see how that will help. In the meantime they are ordering me a replacement computer, but were unable to run diagnostics on the new 2018 machines and are waiting on information and direction from corporate. I hope that corporate is listening and taking measures to fix this issue. I don't see how a replacement machine will fix the issue now that I've finally found a forum where hundreds of other customers are also having the same problem.

Did you ever get this resolved? I'm experiencing the same on iMac Pro also with Logic Pro X, Quicktime, You tube etc.... ongoing support ticket with Apple but no answers or fixes.

Got my Mac book pro 13” beginning November at the Berlin apple store in Germany had the same kreck sound and got today it replaced for a new one at the same apple store in Berlin. After expland 6 hours installing everything again, I am a music producer!!!! I got after q hours found music the same creep noise again!

I can send to repair and will take me 14 days maximum to get it back, any way will works that?!

Don’t think so....

Funny. About 2 months ago someone posted a very similar solution: change the audio here from the default 48k to 44.1k. I did that and it fixed the problem! 100%, and ever since, except.... A few days ago I did the Security Update 2018-002 (OS v10.13.6, High Sierra), and lo and behold the problem came back! So we know absolutely that this is a software problem! A SOFTWARE problem. Getting a new replacement machine with the same software level is pointless. I went back to Audio MIDI Setup and tried changing the MBP Speakers setting back to 48k just to see. Each time I changed it to 48k it jumped back to 44.1k, repeatedly. And the problem remains!

Same here. Spend 4.5k € on a MBP 15'' and have those crackling sounds after about 30/45 minutes of any audio playback. Running 10.13.6 and won't upgrade to Mojave since it's buggy as well.

Got my topcase replaced by a service partner - no remedy. Apple Support employee told me they are aware of the problem and that hardware replacement won't help and that apple's engineering team works on a software fix.

Here's a video of the issue

I'm having the same issue. Speakers randomly crackle. I've noticed it seems to do it also when two applications are playing sound at the same time. For instance, if I'm playing music and then I get the "ding" from an incoming message, it will crackle.

I talked to Apple Support today about this problem on my new MBP 15". I was running High Sierra and getting this defect every 10-15 seconds in GarageBand. Literally a machine fart. The person at Support offered to replace the machine (no possible way!), then to tell me how to reinstall the OS (she had to be kidding!), and then I asked her if she knew about this bug. I told her everybody's got it, that the bug is already world famous. She hemmed and hawed a little and went to ask someone else. She came back and said that Apple says Mojave fixes it. I was skeptical but installed Mojave, which was totally straightforward and works just fine. I've run GarageBand a few times already, played my music, and so far no gas! So if you have this bug and you're on High Sierra, give Mojave a try if your machine supports it.

I work with audio for my daily job with Logic and many other applications. I work for at least 4 hours per day with my MacBook Pro 15” 2018.

I had the problems you describe for a month when I bought the machine in July. After the High Sierra update however, I have not experienced it ever again.

Now I’m on Mojave and still problem free.

I would contact Apple if I were you, because the problems should be gone by now.

I am having the same issues using Audirvana, VLC. All is well for maybe an hour, then crackes begin and become more frequent. VLC will crackle and also suffer dropouts. Temporary remedy in all cases is to quit and restart app. Then you get another 1-2 hours until it starts again. With Audirvana, no change with various converters, Apple Core or not. Hope this gets fixed. os 10.13

Hi all- Updating to Mojave should fix this. I had this issue on High Sierra and early versions of Mojave but as of recent versions there has been no issues. Please make sure your OS/firmware is up to date if you would like an “immediate” fix.

I Started a Youtube Channel Documenting Issues Related to this.

The Goal Is To:

• Create public awareness about audio issues.

• Create a public record of T2-related audio glitches.

• Provide a video hub for people to take their issues to Social Media.

Same problem. Talking to tech support right now. He doesn't seem to have any ideas.
