MacBook pro hissing speaker

I have the same problem, and for a 3000 USD machine this is completely unacceptable.

Apple, please let us know if we need to bring our machine to a genius bar to get this fixed, or if we need to send our Macbooks in for repair.

I'm seeing the exact same thing on my Macbook Pro 2016. I thought there was some issue with the speaker, and because I had a charger failure at the same time (something wasn't charging), I took the MBP in to have a look. It passed all of the hardware test, so I guess it's just a design flaw?

The Apple technician did mention that you'd hear hissing sound if the voltage wasn't right (I had charging issue at the same time and wasn't sure if it was related). Hopefully this is something they can fix with a software upgrade.

I tried to see if the same thing was happening on my old 2012 Macbook Pro, but with the fan and HDD running loudly, that kind of noise is hard to notice - so maybe this has only become a problem because of how quiet the new laptop is? 😁

Also having the same issue. I heard it on one in the Apple Store and the sales guy gave Me some flannel about it being caused while it is being charged. Total nonsense... it's doing it right now and I'm running off the battery.

I thought it was the fans at first but it's definitely not. Hissing noise appears when you switch applications and then if you do nothing else it will vanish 20 seconds later. It's very quiet but very annoying all the same.

Anyway... no doubt the fix will be hidden away in an update in a couple of years.

Cheers,

Ian.

I have the same issue, I guess is some kind of "gain" applied to some frequencies in the new speaker set. That sound is also noticeable in High-Def headphones, followed by a small click sound when connected to 3.5 audio port.

i have the same problem, this is a white noise coming out from the speaker, i tried to make a video on it, but is not that loud to actually hear that, this is the video. ( i have the macbook pro 2016 15" with touch bar)

Are there any updates on this issue yet? (Because I have the same problem on a MacBook Pro 15" from 2017.)

I am still wondering why there a so few complaints when it seems that this is a general issue of the MacBook Pros with TouchBar.

Yesterday at the store a brilliant genius from our (not anymore) beloved company told me, I swear I'm not making this up, that the hissing noise is a feature to prevent sound distortion while reproducing content. 😐 I mean...this is beyond. And every 15inch available on site was emitting this wonderful trait. Thank you apple, only 3k and everyday it feels like standing by a river in the woods. I hope one day someone will address the problem.

Exactly the same thing on the same model, i tried a pram reset without success...

Yes the level is very low but noticable. It will be interesting to try on windows with bootcamp. I monitored the speed fan with iStat and i didn't notice any increase during the use of the speakers. I think this noise really comes from the speakers. When i put in charge the mac when it is off, it makes a sound charge like iPad or iPhone with no noise.

The first MacBook Pro 15 late 2016 that I bought had that issue. I asked for a replacement and the new replacement has it as well. I hope its software related.

Have the same issue with MacBook pro mlh42. It appears apparently and stops after 10-20 seconds. Very annoying
