My MacBook Pro 2018 version speakers are crackling.

Hi ehsanw97 and everyone,

My new 2018 MBP (15" w/ Radeon 560X) is also experiencing poor throttling behavior in Boot Camp.

While playing a game, I used the Radeon driver's onscreen display to track GPU clock speeds, and for seemingly no reason the clock speeds are being throttled very aggressively, leading to really poor performance.

My previous MBP (the 2016 model) had a less-powerful GPU, and yet it played the same game in Boot Camp with excellent performance. So this is clearly some kind of issue with the SMC/T2.

Yea I think I’m going to have to do the same. When I told them to google it they say this means nothing and that they only go by reports made to Apple care. They say they don’t even acknowledge their own forum here. Agreed, it definitely disappointing.

Just because you have reinstalled everything and it seems to be fine doesn't mean it isn't hardware. It means that when the machine is under no pressure just playing off iTunes or the internet it performs fine.

I haven't ever opened logic, GarageBand, Blender or any other program mentioned in this thread. I have only used one thing and one thing only and that is Traktor (another audio program made by Native Instruments.) So to make it clear two brand new MacBook pros 2018 with Zero things installed apart from Traktor.

It doesn't change the sample rate and no matter which sample rate I use the problem returns.

In the US you have 2 weeks after purchase to exchange it if you bought it from Apple. I'm not sure what options other countries offer. The options vary according to legal obligations imposed by respective governments.

It doesn't look like replacing it will solve the problem, that assumption is based on posts in this thread, but it's worth a try. At minimum the processing of returns should help bring this issue to Apple's attention if they aren't already aware of it.

Social media is a good idea. All companies loath bad publicity.

If this was a small deal then they would have just released a quick software update and everything would be fine. Instead with all their genius engineers the best you get is that their might be a solution in a month? My friend who works for Apple knew about a couple weeks back so they have been known about it and have failed to come up with anything. What a joke. They won’t issue a public statement because they don’t want to recall their machines.

Yes. Thanks for the info. But now i know all the steps dont do a **** about this issue. So lets see what we are going to face a recall or a repair or a software repair. Let's hope for the best i don't want to return it again and wait a couple of weeks to get it. Will soon do a video as well and reproduce the results. 🙂

same issue here 4 days after brought the new one 15", when I play SC II, the sound is cracking, the volume is at the minimum level, laptop not super hot. I have to quit the game to solve the issue. Also notice that when I play the game the airpods cannot get the sound correctly, not happening when listening to music.

i have updated using the update but im still waiting , the issue only occurs for like after 30-40 mins. I did however speak with a senior adviser at apple today and they have been handling my case and they told me that if i take my laptop into the apple store i am eligible for a full refund. Now im not sure if i should do the refund and wait 5-7 days to get the money back and buy a new laptop or if i should wait and see if this update has fixed it.

Another issue that the supplemental update fixed is the disappearance of "Wallet & Apple Pay" icon, if you restored the machine with Time Machine backup from another earlier-gen MacBook.

Just a quick little something I noticed...

I updated earlier tonight. Decided to watch a movie, and noticed the screen flickers quickly, every 5-10 minutes. Is anyone interested in testing this out as well, and keeping an eye out for it? To clarify, AFTER the update, screen flickering occurs while watching a movie (ON ITUNES).

I have watched movies previously on this computer (2018 MacBook Pro 13 inch) through iTunes, and never noticed this issue until tonight.

I will note however, there has been no speaker issues whatsoever during this movie. (Avengers: Infinity War -- so, a fairly long test 😉)

So maybe it fixed one issue but created another in the process. Hopefully some other people can sound off and we can find out if this is just us or not. We might have to check other threads since this is technically potentially evolving into an issue that is different from this threads topic.

Hi Mike, can you please let me know if you get any issue again, i still have 5 days more to return my macbook pro i5 2018, or make complain about it again, this is my second macbook i already went returned the other one the got the same issue then this.

im really upset about this problem, one because they don't give me any resolve and the other reason because i pay almost two thousand dollar.

thanks

Same here. No more sound problem after almost 2 weeks.

However still have the flickering issue mentioned by @Haunts. I just did a "Capture Data" with Apple so they can analyze my whole computer and hopefully find a solution...

The cracking sound disappeared on my MBP 15" when I listened iTunes after I installed the supplemental update 2.

However, when I am using Logic ProX, problems are still there.

Even actually I was not using any headphones, suddenly the cracking started and a notice screen jumped out saying
"Error while trying to synchronize AUDIO and MIDI", screenshot as attached.

Then I put on headphones, either wireless or not, cracking sound disappeared at first for a while then appeared again.

I already returned my MBP and got a new one, but the problem is still the same.

Please let me know what to do.
