Your device supports Hi-Res audio _output_* (at least 24bit, at least 96khz sampling rate), but Poweramp v3.0 alpha doesn't support it?
Request the support here! Please provide (requests without these items will be deleted): Device model ROM version (Android version, stock/OTA/Custom ROM) Why do you think your device supports Hi-Res (link to device features, etc.)? A copy of your device's /etc/audio_policy.conf file may be helpful. [Edit: on some devices this can be found in /vendor/etc/ or /system/etc/ instead] * Please note, this is for Hi-Res output requests, just playback (with resampling) of hi-res audio is already implemented by Poweramp v2.0 for all devices/ROMs.
