Crackling sound on MacBook Pro 2018

I went round and round with Apple Support a few months back regarding this issue, and eventually it seemed that the problem went away with my initial Mojave upgrade.

However, in recent weeks, and especially with the release of 10.14.2, the crackling and popping has come back more frequently.

I think we need to resurface attention to this issue, as there is something seriously wrong with this 2018 round of MBP's.

Awaiting further developments...

Theres a Youtubevideo where the guy explains how to fix this problem, with quitting the coreaudioprocess.

• Go to Spotlight
• search for the activity Monitor and open it
• filter to "coreaudiod"
• double-click the process and quit it

The audio should run normal.

Here is also the link to the video

This helped me instantly, but its not a real solution. Apple should fix it with an update!

I Started a Youtube Channel Documenting Issues Related to This.

After all the updates, the supplemental update 2 and Mojave, I too still have this issue. I'm a music major and I need to bring my macbook to my lessons every week and play my pieces out through my speaker but I'm afraid the speakers will blow out. I still have no idea what the fix is but I've brought two macbooks back and am on my third on but still the same issue occurs.

I have the same issue with my MacBook Pro 2018 13', I've contacted Apple support but the only thing they could help me with was to make a re-installation of Mojave with the hope that it would eliminate the problem, no success.

I have a month with my new Mac and the only thing that bothers me is that I cannot listen to music while working, I spend a lot of time working with the computer and it is very disturbing for me whenever I hear the crackling sound. It happens on both speakers and headphones.

I'm at the Apple store right now returning my THIRD 15" macbook pro in 45 days. I've had the issue with multiple apps (zoom, itunes, netflix, chrome, etc.) and have only found temporary relief by restarting my computer. They keep telling me it's an anomaly, however that doesn't seem to be the case. I'm so upset.... I don't want a different laptop, AND I'm sick of being at the Apple store constantly getting a new laptop and having to take time to set up new laptops constantly. So I'm downgrading because I need a laptop that works - unfortunately that's more important than having the laptop I want at this point.

Hi Alias98.

You are not alone with this crackling issue. I have the laptop over 1 week only and found the noise in the 4th day even if I have the latest updates for High Sierra. Didn't go for Mojave yet. Some say Mojave will fix it, but I couldn't really find users that previously wrote about their sound problem on these conversations, to come back and tell us if they fixed it or not, and how. Also the others that are saying they are in touch with Apple, they don't come back with anything official or 100% fix.

In the meantime, could you please tell us beginners into Mac, how/where do you change the sound sampling from 44 khz to 48khz?

Thanks

You can change this setting in the "Audio MIDI Setup" app, located in the Utilities subfolder of Applications (/Applications/Utilities/Audio MIDI Setup.app).

The setting can be found in the "Audio Devices" window (press ⌘1 to open/close this window). Make sure the speakers are selected on the left, then on the right, select the output tab, and change the sampling rate in the Format pull-down menu to 48,000 Hz. Perform the same change for the Microphone on its Input tab.

My 15" MacBook Pro running on Mojave 10.14.1, purchased in August, just started with the crackling speakers issue yesterday and I wasn't playing music. I noticed it from the "notification" tone. 🤔 I restarted my laptop and it sounded fine until this morning. Now I see that others are experiencing the same problem.

I don't have time to replace/repair my MacBook right now.😭 Please reply if yours start acting up again, BriSeeley? Would appreciate any help or guidance from others.

Thanks much!

I have bought a new macbook pro 15 2018 and noticed this issue after a few hours listening to spotify.. it occurs randomly a few times then I can listen once again for some time and then it comes back... How can I even present the problem to Apple and prove it's happening if I can't show it to them right away?

I'm not sure yet... I did some security update apple suggested and changed audio midi setup to 48khz as someone suggested listening to spotify for around hour and a half nothing happens.. yesterday it happened after a few hours also It's new macbook I didn't use it almost yet at all... I will run tests and see what happens

Just chiming in to report that this has been happening to me for about as long as I've had this MBP - maybe two months for now. Haven't upgraded to Mojave yet, but multiple reports seem to confirm that it doesn't fix the base issue. It kicks in multiple times a day, rebooting usually helps for a while. Spotify and Youtube audio are unlistenable but surprisingly Ableton Live doesn't suffer from this at all (fingers crossed).

I kept listening and testing mostly with spotify it played today for an hour then started making this crackling noise and then I closed spotify and opened again it's working almost an hour right now again... what are you doing about it now?

I got this problem too, only with Spotify, and it starts around 30 min Spotify has been plating in the back. As a hint for @apple this issue started only after I executed garageband for the first time a couple of months ago. The problem arises even when garage band is not being used.

I also had this problem only with spotify as for now.. tried watching movies online for like 2 hours not a single crackle with Chrome browser... also I kept listening to spotify on and off and didn't catch anything... but like i said last time it happened after an hour or so.. and after rebooting Spotify App I played for another 2 hours and it was ok
