Miui 8 6.7.7 beta
Flashed using twrp

I Have the issue that the volume of the earpiece is way too soft on the maximum setting during calling. When it is really quiet I can understand the other side but not when outside or at the office.

The engineer mode doesnt seem to support anything to change it. When doing the test it is actually loud.

Reset and clear cache didnt help.
Android4viper didnt help, cant set anything for the earpiece.

How can I increase the volume?

I tried some changes in the settings in mixer_paths.xml in /system/etc. Unfortunately it doesn't have any effect. The files also looks different than the examples I can find on the internet. Does anyone know what setting I need to change?

I tried a few ROMS, the volume is better (acceptable) with the xiaomi.eu v7 version and also the ManhIT SpaceX v8. However it's still quite low on maximum if you ask me.
