HTC One M7 Speaker Problem

[kopplare]

Okay, so i've had this phone for 2 years (HTC ONE M7) and i've dropped it once almost a year ago.
Recently i noticed my bottom speaker doesn't function anymore but this is only after i unplug my headset or any aux cord. If i want it to function again for better sound quality i have to restart my phone and sometimes it gets very annoying.
Anybody knows whats going on, or if you had this problem how'd you fix it.

Welcome to Android Central! That would make me wonder about some kind of loose connection internally, which would be difficult to address, given the unibody construction. Does it happen in Safe Mode? https://support.t-mobile.com/docs/DOC-11779
