Video of the work at https://www.google.com/search?q=ifixit+samsung+audio+port+replacement&gl=US#kpvalbx=1 but doesn't show getting down to that part.
It's replaceable for the very reason above. These do fail.
I tried to clean my audio port on my Samsung Galaxy s7 and now i can only hear out of one side of my headphone. Ps my headphones are not broken.
