It worked for me with Poweramp but voice distortion occur.
in my MPM2 the sound quality remain same
It's ok, just close this and open music app which supports equalizer (spotify, google play music, aimp, etc.) and find equalizer settings
ya its working but sound isn't good
Are you on Android 10?
no on A9
This feature will not be included as asus can't increase their cost for adding new features on handsets older than 18 + months
