1. ASUS ZenFone Max Pro M1
2. Stock Android 8.1.0
3. https://4pda.ru/forum/index.php?showtopic=898479&st=3300#entry78306546 and my personal experience with Hi-Res Output option in Poweramp.
Here's a problem: reconnecting my wired headset drops sample rate/sample format from selected 192kHz/24-bit to 48kHz/16-bit. Please, fix that. I'm tired of reconfiguring my Poweramp every time.
P. S. I'm using the latest version of the app.
