I now found the other thread. It was originated also by you: Slow down and distorted speaker audio in zorin os 17.3
Noone could give a solution to that thread, so I doubt if one will be found now.
FYI. I have also done some websearches using "...Ubuntu" in searchterm to try and help you find an answer, but again no solutions found.
If you are dual-booting, does that charger cause any issues when running Windows?
