1. Device model: Samsung Note 4, SM-N910C (Exynos version with Wolfson WM5110E chip) 2. ROM version (Android version, stock/OTA/Custom ROM) Stock Android Marshmallow 6.0.1 3. 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. Pretty sure it does hi-res: http://www.engadget.com/2013/05/17/wolfson-wm5110-audio-chip/, but when I enable hi-res option in Poweramp it just makes popping and clicking noises.
