Speaker problem

I had my mx4 pro’s screen broken some months ago, but replaced it recently just fine.Unfortunately,even though everything else seems to work fine, i have no sound.I even ordered a new replacement speaker just in case, but all i get is a faint buzzing…It really sucks having repaired the screen which is a major problem, not to be able to use the phone for such a minor one :/ Any suggestions? Thank you in advance!


@DonkeyKing are you sure all wires are running fine accross the device? Like no one being stuck or broken or anything like that?
Buzzing noise indicates that there is some contact, where it shouldn’t be.
