I have an Asus C434. I want to sideload moviehd apk

I switched to the Dev channel https://apkbattle.com/winzo-gold-mod-apk/ I turned on Linux. I enabled ADB debugging

using the terminal and ADB, I installed the app file. It works fine... but... when I watch a movie with the app, the volume is very low.

When I use Netflix, youtube or anything else that was not sideloaded in this manner, volume is loud. The apk file i installed is the same version as the one on my android tablet - works there without issues. Tried to uninstall and reinstall.

Any ideas?
