Hi-Res Audio For Android

Posted by tom2tec on

Enable high resolution audio for MediaTek devices up to 32-bit/192kHz (if device supports). This module only changes the configuration on “audio_policy” because most Android devices limit their capabilities to 16-bit/48kHz only, the rest depends on whether the device used supports Hi-Res Audio™ or not.

*applies to internal Speakers & Wired (not for Bluetooth/USB devices).
