Updated to Big Sur 11.5.1 today and the popping is still there, its so frustrating on a $3000 plus laptop to have this issue, and Apple acts like your the only person who has this issue, even though its pretty common... no fix still....

Just updated to Big Sur 11.3.1 and the popping noise is still there, (16inch MBP) very frustrating as it was resolved before 11.3 update.
