I flashed havoc os 2.0 on my mi max 2. It has stereo speaker support. Since i ported to this rom, I can barely listen to someone on call from the ear piece and also the main speaker has decreased the volume level, but while playing normal songs, both the speakers sound loud. on googling, found that it is some low incall volume issue, some suggested changes in system/bin/etc directories but i couldn't find any. I have a rooted device. Can anyone help, i just registered for the same..
