Hi all,
I recently bought a new MacbookPro 16 inch in Dec 2019 and have both these issues. It's a 16gb ram, 512 GB storage and has Logic Pro X added to it. I use my Macbook mainly for music. composition.
This person has a video on youtube that replicates the most annoying audio issue perfectly: https://www.youtube.com/watch?v=NoyXuI0j2BE
Issue: Rumbling sound with certain sounds (rumbling feedback/echo) - initially recognised problem in Logic Pro when recording
Current issue experienced in Logic Pro , Youtube, iTunes and general notification sounds
Issue: MacBooks own internal speakers (not experiencing issue with headphones)
Point 1: problem isn’t just in Logic
Sound - noticed the rumbling sound when I plugged in the charger cable (the short notification sound when you put the cable in or take it out when charging)
Issue within: MacBook speakers only, headphones seem fine
The rumbling sound also happens in YouTube videos.
For example, the harp in Logic and also harp sounds in youtube videos are where I notice it the most.
Progress: Had 3 Genius Bar appointments and spoken to a few Apple tech folks online
Audio test in Genius Bar = passed
Issue still happening after full restore - backed up from Time machine
My next Genius Bar apt is next Tuesday.
I could replicate the ‘rumbling’ issue on at least 1 out of the 3 MBP 16 inch in store today.
Apple chat suggested to even try Safe mode to isolate the issue - https://support.apple.com/en-gb/HT201262
I’m hoping this is software related but not sure yet. My friend also bought a MBP16 inch and it was kind of doing the same thing on his but mine seems to be worse.
Force quitting Coreaudiod seems to fix this very temporarily but then within a few minutes, it happens again.
Will keep you all updated! Fingers crossed :)
I can't justify the amount of money I have paid for this - and I come from a low income background :(
Bests,
Amy
