Low earspeaker volume on LG G5

about 2 weeks ago my ear speaker volume went really quiet even though the volume was cranked way up. Tried cleaning the mesh, tried everything I can find on the internet to test and did discover through a hidden test menu that it shows the volume at 4 and max is 7… But there is no explanation on how to change it. I was able to make the volume a little louder when dialing my voicemail but the setting doesn’t stay loud. Physically the volume rocker works and has no issues going up or down on all other volume settings.

I almost threw my phone on the ground a few times out of frustration…

Help!
