Audio output on android device

Hello, basically my loudspeaker is broken so i bought new one, but it takes about 3-4 week to deliver. For that time i managed to change audio output for media to earspeaker but i would like to change also alerts(notification and ringtones) to play from earspeaker. I am using app called SoundAbout and there you can set alerts only for headsets and suff like that. I wonder if there is another way to completly swap speakers or something so i can hear when sbd is calling me.
I am using Xiaomi redmi note 4g, android 5.1.1. Thanks for every suggestion :)
