1. Device model : POCO X2
2. ROM version : Android 10, MIUI 11
3. Why do you think your device supports Hi-Res (link to device features, etc.)? Audio IO Policy attached. Also SD 730G Qualcomm page talks about PCM 32bit/384k.
4. For recent Poweramp builds, screenshot of Settings / Audio / Advanced Tweaks / Audio Outputs Detection Logs : attached.

I must add 24 bit works but there's no 32 bit option, also the volume when I enable 24 bit audio is lesser than 16bit and upon enabling DVC it decreases even more.

Please go to Audio => Output => Hi-Res Output and hit Restore Defaults. Also check if you have DVC enabled as from your description you have it Off (DVC should be indicated under Poweramp frequency analyzer). Generally, Xiaomis on Snapdragon works fine with Hi-Res and DVC.

True true, I had turned DVC off a couple days ago. Turning it on increased the volume alot. Thanks.

Model : Xiaomi - MI MAX  - 1st gen

System : MIUI Global 9.5.2.0 Stable (not rooted, bootloader unlocked), Android 7.0

Why should it work :

Snapdragon 24 bit PCM; It worked on 703 alpha in Android 6, notable boost in volume and the lows.

In the newer versions, the soundstage decreased and there's literally no bass.

Here's the audio_policy
