Macbook Pro 16 inch speaker pulsating noise?

Do you think if I de-installed Garageband it would disappear?

You're on the other side of the divide - as in, you cannot return yours anymore - so I hear

your logic from that place. I am still within warranty (on #3) and am wondering, since I use

such a simple program if it might be better to digress in laptop model or go PC.

There is a guy named Patrick, the Garageband Guide, and he says to avoid Catalina at all costs.

Something about 64 bit screwing things up and making DAWs unstable and buggy.

I did install Logic with the first computer and the speakers had issue there as well. Probably

after I used G-band.

Thanks for your message and explanation. It helped.

Spoke with Apple support. We collected more diagnostic information. I haven't convinced them to attempt a reproduction on their side, yet, which is a bit disappointing. But we did capture new diagnostic information, and I have another appointment to follow up with them next week.

I'm going to continue pushing on this with my support engineer, and continue pushing on them to reproduce it themselves. The key to getting a fix is an Apple engineer, reproducing the issue for themselves. Then they can test and measure the issue themselves.

Sorry to hear...I imagine you have looked into the sample rates?

I don't even know those programs - will look into them.

All in all though - are you willing to go to an older MBP and work in Mojave

or something like that? Or will you stick with the 16 inch?

I tried diligently to reproduce the issue before installing a DAW, and I couldn't get it to happen. I'm not saying it's impossible, but I still think at least installing a DAW is an important step.

MobileComposer, from whom did you hear this was a known issue that Apple was working on? I ask because my support rep, that I've been working with for a few weeks now, was not aware of any known issues. It might be useful to consolidate the case if there are multiple cases with the same issue. If you have a case number or anything that would be helpful.

I'm talking to my support rep this weekend and will give an update after the call.

I have this exact same problem - had it since day one (i.e. when the 16 inch was released) , please post if you get a resolution with the Apple engineers. Its so annoying when trying to just mess around with Logic without headphones. Seems much more prominent on low frequnecy simple bass sounds.

hope so! I produce in logic and even with everything on all the latest updates, it's unusable if you're just trying to reference and mix off the built in speakers. super frustrating and unacceptable for a machine of this price point. definitely looking forward to a fix from apple

I weirdly don’t have any of those problems after I changed the settings, but I have this problem on my iMac Pro now after the newest Logic Update with every speaker or headphones... This drives me crazy

I'm delighted I found your thread as I've been having exactly the same issue with Logic. I thought at first I had an effect enabled. the problem goes when I plug headphones. Did you get anywhere with a fix?

****, aizarged just broke the theory then.

But THAT is still weird, how a software related problem can happen on like 1/2 of the computers or maybe more...

The only thing different about Apple stores' computers is that you don't put your fingerprint on them and set them up.

The problem is indeed on Garage Band and Logic Pro... Or any software like Final Cut... Yes it's been tested on both garage band and Logic Pro at the Store.

It could be cool that one of you try and see a bunch of computer at another Apple Store. Because if we can find that 100% of them work properly...

Man, with that info we'd kill them.

The only thing different about Apple stores' computers is that you don't put your fingerprint on them and set them up.

I'm sorry about breaking the theory, but here we have another one. Will try to visit Apple and try to replicate the issue ;)

"she said that there’s no record of this issue on their side"

Are you kidding me????

I can point them to a thread on gearslutz that began on 1 Dec 2019 about the same issue.

Not to mention threads here!

I bet they don't give me a new machine in the next 12 months and I only just got it on 30 June 2020 and had the issues from day one.

It's the type of issue that needs a class action.

Yeah. I asked my advisor guy the same question: Is there any record of this. He said he couldn't really look up other issues, so he didn't know. If you speak with your advisor again, my case number is 101046325864. If you share your case number I may ask them about it too if they reach out to me.
