Internal DAC usage

[Nkirk]

Thanks for the answer. So inorder to get the best sound quality i should have the hifi toggle enabled from Android and select the custom driver from player.

That solves the volume steps isuue as well, as when hifi mode is enabled 80 step vol mode gets activated since Oreo.

Hi impedance mode get activated automatically when such headphones are plugged in which increases the output levels. You can force enable it using build prop, but generally not needed though.

Thanks
