Muffled speakers on MacBook Pro (15-inch, 2017)

Hi,

i'd like to update a thread about the speaker problem occuring on various MacbookPro models (including the MacBook Pro (15-inch, 2017))

Whenever playing audio that reaches a certain volume the internal speakers would become muffled.

The original thread is here -> https://discussions.apple.com/thread/8014046?page=9 It seems there is many people with the same issue...

Did anyone find a long term solution for this ?

Thanks for your help !
