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

Guys, just to reply this issue. Unfortunately this issue is only fixed by replacing the entire MacBook Pro body (the case itself, not its inner electronic components). It appears that Apple does not consider this is issue as an issue that is supposed to make this replacement for free with the Mac having its warranty expired, but what happened to me is that I sent my Mac to check this issue, but the guys from the official Apple store told me that my battery was kind of stewed, and this was enough for Apple to replace my case for free which fixed the problem.

I took mine yesterday to an authorized dealer and immediately he told me: "ah, we need to service it. iIts probably the board"

Maybe it happened already with some other custo

I have this issue too.

Except my left speaker is permanently muffled. The trick with "Audio MIDI Setup" temporarily fixes only the right speaker.

I've called Apple Support. I have tried all the software tricks to fix it. I even tried to boot a fresh OS from USB (the original OS shipped with my model of MBP). We figured out this is most likely a hardware problem.

I have 13 months old MBP (the warranty just expired). I need to take it to service 😟

MacBook Pro (15-inch, 2016)

OS 10.13.3 (17D102)

Via command line you need to run the following:

$ sudo killall coreaudiod

From time to time it will require you to enter administrator password, so it is not very convenient as well

For me the MIDI app is instantly fixing this issue.

On that topic, does anyone know of a way to change the rate 44k/48k hz through the command line or so? So that I don't need to open the app time.

When video calling, there is often a lot of mic interference and this is driving me insane at the moment.

Same thing has happened to me as well, on my 2nd machine. Had to get the first machine replaced, out of warranty. Figured it was a one time thing because the Genius bar said that it was not a known issue at the time. Has now happened to my 2nd MBP with touchbar so it clearly must be a defect in the device.

Here's an update about some of the issues I've faced.

So I contacted Apple support about getting this thing repaired and I was instructed to take it into a store. I took it to my "local" (hr away) Apple store and all I was told was that because the entire $800 top case was replaced a year ago, I was told to contact AppleCare and wasn't even given an option to repair in store. Called AppleCare and they basically told me they can't warranty the new part. I guess as apologies for going an hour away for literally nothing, I was told the left speaker repair would be covered.

When I got my machine back, I discovered they had basically replaced every single part on it (for free) and given me a brand new 2016 MBP. This is now my 3rd 2016 MBP so we'll see if this one has issues too. If it does, I guess I'll be selling it and buying a windows computer to run Linux on...

Have anyone tried an app like 'Audio Hijack'? It can route the sound through various filters, including limiting the max db, "de click" and so on. For various reasons I can't test it right now myself.

I ran into this issue on my 2016 MBP 15" with touch bar.

I reset NVRAM and SMC and this fixed the issue today. I'm hoping it stays fixed... I'll attempt to put an update on my post here after a few months to say whether it was a permanent fix for me or not.

I went to the store and they said it's 400 to replace the top panel plus 75 service fee, so fixing this speaker problem is pretty expensive if you ask me

Hey, same issue here. It started back in august 2017. We have this stackexchange thread here too: macbook - Sound from the speakers of my MBPro with Touch Bar degrading - Ask Different

Same computer, same problem. Similar things temporarily solve the problem.

Opening Audio MIDI setup for example and changing the hz of the output will fix the problem unless the volume moves again. (image shows headphones, because I'm currently using them, but problem is not with headphones)

Had this issue for the last 4 months on my Macbook Pro 15'' 2017. On 10.13.2 now and the issue persists. I hoped it would be a software problem, but I guess I have no choice but to take it to the service.

I am having these same issues. So frustrated. This is the first of many Mac devices that I have wanted to throw in the garbage. Due to the lack of communication or attention from Apple... and that it is not covered under a recall as of yet, I am considering starting a Class Action suit. This is ridiculous. I purchased this machine for work. Part of my work is audio editing. As you could probably understand this problem is costing me quite a bit of frustration and hardship. PLEASE FIX THIS OR AT LEAST REPLY WITH A SOLUTION APPLE.

I have this problem to, bringing it in to get serviced in about 5 days. pain in the *** as I use this machine for work and cant afford to be without it for 5-7 days. Nothing software related seems to fix it.
