Volume triggered Muffled Speakers - 2016 MBP 15” Fault (w/ Video Demonstration)

I have 2017 15" MacBook Pro. Same problem, speakers sound super muffled and terrible, after going over a certain volume. It's incredibly annoying, will take it to repair. Also my display lid makes a cracking noise when I open it and sometimes just randomly without even touching the laptop. Disappointed!

I have the same issue. Brand new MBP 13" and the problem started from day 1 on the left speaker. Have gotten the speakers replaced from Apple twice but the issue is still there. Apple says they can't do anything more than this. Help!

I have this same problem on my late-2016 MBP 15" with touch bar.

Just happened 2 days ago and the best part is that my warranty is expired...

I can't believed this, first there was the keyboard issue then now this...

When they told me that Apple was expensive... I didn't listen.

This laptop is not even 3 years old, I expect more when buying an Apple product.

I should have bought the Apple Care plus, stupid me...

I will call Apple tomorrow to see if they can help in any way and will keep you guys posted.

Hi Matt,

Can you tell us whether 2 years on you have managed to fix the issue?

I have exactly the same issue as you (MacBook Pro 15-inch, 2017), but it appeared to start when plugging in the power cable into one of the USB-C ports on the left side. I heard a crackle noise and I always assumed it somehow fried the speaker as it only happens to the left speaker.

I have an appointment for this Friday at the Apple Store, but any update from you would be great.

Thanks!

Hello, was anyone able to have Apple repair the muffled audio/sound issue on Macbook with no warranty?

I just bought a used 2017 MBP15 with a larger SSD because my other 2017 MBP 15 was running out of space and found the one I just bought has this muffed audio issue. I got it for a good price from Craigslist so really want to keep it if Apple would make a courtesy repair - out of warranty.

Hello everyone from Russia! A year ago, I bought a macbook pro 15 with a touchbar. And today, as with many people, a small crackling sound was heard in the left column when the power was connected. Then everything is like everyone else. Some software solutions partially solve the problem, but in general, everything becomes backwards. But I want to say that here in Russia where there is no democracy and freedom of speech, we will not be able to influence APPLE. Therefore, I ask you my American colleagues to get them to make a return program! I work with video and when I come to clients I have to show video with sound, do I have to carry speakers with me? How do you imagine this Tim?

I am also having this problem with the Macbook Pro 2017 15". I tried changing the midi format hz but it's only a temporary fix. I am amazed how many people out here are having this problem. It this falling on deaf ears? I don't know how I can keep justifying spending this kind of money on these machines and having problems that aren't addressed. Apple, what can we do about this?

I can confirm the issue is still there.

It think it is even worse, because some times the sound is completely dead after waking up from standby and cannot be repaired by "sudo killall coreaudiod". Wether Chrome, iTunes nor any other app play any sound. I have to restart the CrapBookPro to get sound again.

Same problem for me. I have a 15" Late 2016 MBP w/ Touch Bar, running macOS Catalina 10.15 (Up to date as of the writing of the post–I just installed the Oct. 15th supplemental update).

Often times, when I am watching a video on YouTube, the audio coming from the internal speakers will just randomly get "muffled", and stay that way for a period of time. I am not sure what causes it to happen or when/why it stops... and it doesn't seem to happen when I am streaming on a site like Netflix or Xfinity Stream though...? Very strange. I really need this fixed as the issue tends to flare up when I am at work. I need to play a videos at a decent-enough volume for everyone in our small office or in a small conference room to hear on a fairly regular basis and it's quite frustrating when the audio goes haywire halfway through–and stays that way.

Plus:

I am also having the issue that many others on this thread have referenced regarding the keys on the keyboard getting somewhat stuck or blocked... some keys, seemingly at random, will cease to have the amount of travel they are supposed to. With this keyboard, it's not like I can just easily use a pressurized air canister to push out any debris or dust that might be causing the issue like I used to on my 15" Early 2011 MBP. Dust or debris are likely the culprit because the problem is never permanent.

Additionally, I get an issue where keys tend to double tap even though I only hit them once (For example: every time I hit a given key, say the "b" key, I end up with "bb"). This issue tends to last on average for about a week.

Both of these keyboard issues are extremely frustrating... imagine typing in a password and not knowing if a keystroke is A. registering or not, or B. if one is doubling up on its own.

Same issue here. Apple, please address this.

Same issue with my son's MBP. The MBP is just a month out of warranty and they offered to fix it for $400. Has Apple covered this for anyone that's out of warranty?

Heading to the Apple Store on Saturday to see what is happening.

Keyboard issue as well. This machine really is trouble... 4 issues and 2 replacements already.

This is also happening to me, trying Bryan's solution fixed only 1 speaker, not both, this is weird and frustrating, I find it odd that so many users are experiencing this at the same time.
