I'm hearing myself instead of other hand during call.

I'm using LineageOS 7.1 for my S4 mini. While calling someone else there is no sound coming or going. I'm hearing myself sometimes. Call is working just fine but there are no voices. I wiped the phone cache but that didnt seem to work. How can I solve this?

Is it to same if you switch to speaker or use a headset or Bluetooth?

The weird thing is it's only happening sometimes, not everytime. It's like the voice goes off when I bring the phone to my ear. It's not happening everytime so I can't figure out the reason.
