Mic and headphone wont work after lighting port replacement

Hey guys recently my SE stopped turning on because it wouldn’t charge, i’ve had the phone for about 5 years since so i replaced the battery and the charging dock in one go battery worked fine but every time i install everything it boots up and charges fine but the headphone quality is very jank, and both bottom and headphone jack microphones wont work; tested all with voice memo

thinking my lighting port replacement was a dud or maybe i wasn’t properly grounded the first time i ordered another lighting port replacement and the same thing happens

Whats going on is the grounding washer on the cable by the headphone jack the cause of this issue? i’ve completed this repair on a 5s and never had the problem

please help i haven’t had my phone since Christmas
