stock music player (as well as many generic music player apps) can playback 24bit files in DIRECT mode without SRC, dumpsys media.audio_flinger while playing 24/44 in stock player is attached. however 16bit files will be resampled to 16/48 in MIXER path with those players.
Hi-Res option in Poweramp alpha 704 does show up, but doesn't work, always "Failed: Poweramp Hi-Res Exp Output" no matter which output sample rate or buffer size I choose.
