Macbook pro 16" M1 pro 2021 popping sound OS 12.0.1

Hi, I just got my Macbook pro 16" M1 pro 2021 over a month. It is on OS v12.0.1. It is a great machine. But it developed some popping sound today. I played some Spanish guitar music for around 1.5 hours (not at the highest volume) then it randomly developed some popping sound on the right side speaker. When I lift the mac and tile to the right to listen closely, the popping sound is getting worse and constant, especially at the high pitch. When I put it down the popping sound still existing but less even when I put the volume to 4 bars. Apple support suggested to upgrade to OS to12.1. After upgrade the popping sound is gone, even at the highest volume. Is it possible that the OS upgrade fix the issue? (i.e. limited the frequency range?).


I see some discussion that the popping sound comes when cpu /memory is high. In my case, I only open the apple music nothing else.


Has anyone see the same issue?

Thanks

DON'T SEND IN YOUR DEVICES! It has nothing to do with hardware. It's a software issue. What you hear is rosetta not being able to keep up translating the audio-stream therefore loosing samples, which makes the clicking and pooping sound.

There are no solutions at the time being coming from apple. It has nothing to do with the hardware. It is an issue with rosetta, aggregate devices and/or buffering of the Audio.

There are some workarounds though. If you install any software core audio drivers (mixup audios' decibel, sonnox's listenhub or something similar) the problem goes away immediately and doesn't return when you set the sample rate buffers to a reasonable size. So unless you run nothing (not even one process) that needs rosetta, this problem will not occur anymore. Apple won't fix it and will hope complaints go away when in 2 or 3 years everything runs natively. It's a shame but that's how it's gonna be, I fear.

I am a professional audio engineer and read a lot about it in the apple dev forums, so if you dig deep enough you can find the causes and get a picture what's happening. Best solution if you need rosetta is using a third party core audio driver that buffers the audio after it is "created" by the os (grab's the zeroes and ones) and then hands it over to the speakers. This extra layer of calculation seems to introduce the necessary latency (slows the audio-stream down) so that rosetta can deal with it calculating it in "real-time".

My crackling only started about a month ago (December 2022). It happens regardless of whether applications are open or not, whether Internet is connected or not, whether anything is playing or not, and it is intolerable. It crackles more loudly and intensely whenever I perform a command and whenever it performs a function, whether I’m hitting an f–key, waiting for an application to open, or even when I just move the mouse around.


MacBook Pro 13” mid–2012,

macOS Sierra version 10.12.6, all software fully up-to-date.


I took a video but I guess we can’t upload videos here? A screenshot would be of little use for a problem like this.


Best wishes, happy new year, best of luck to all

For me the issue applies to when I'm wearing headphones, and through the internal speakers, so I don't believe cleaning the internal speakers will affect the popping noise in my Bluetooth headphones

Different problem entirely - the solution I proposed relates to the internal speaker in addition to:


« PROBLEM: Crackling and popping on Right OR Left speaker during "bassy" sounds. Software updates and sample rate changes fix nothing.


Note: Generally, software issues will happen on both sides as the sound engine should be sending the same signal to all speakers. »


In other words, it’s rather obvious that cleaning the internal speakers of the Mac for the specific problem I mention will not fix your Bluetooth speaker problem but it will help other people who’s problems are not like yours [=


These kind of issues can be from different sources. That’s why we troubleshoot and try to find out the issue. I have Bluetooth headsets that work perfectly, so you have a different problem entirely.

In December 2022, I purchased a MacBook Pro M1, only to encounter an immediate issue—a distracting throttling sound emitting from the right speaker. Though I temporarily remedied it by force-quitting Inter Processes via the Activity Monitor, it proved unsatisfactory.


The root cause, as discovered through discussion with a technician, lies in the MacBook Pro's design: two openings flanking each side where the speakers are situated. Should any metal object come into proximity with these openings, the speaker's magnetism may draw it in, resulting in the unwanted sound.

The solution entails delicately opening the MacBook (do not open if you have Limited Warranty) and removing any foreign objects ensnared by the speaker—a process essential for restoring optimal audio performance. While specific to the MacBook Pro M1, it's prudent to remain vigilant for similar issues in subsequent models like the M2 and M3.

Yes, I have a similar problem for about 3 years in my macbook pro 16 m1 and it still no one has not solved, no one cares about your problems, they want you to buy their products for thousands of dollars but do not want to change anything, I heard that in macbooks on m2 similar problem, that is, they even in the new macbooks did not deign to fix it, I do not know how things are in the macbook m3
