1. Tmobile LG G5 (H830)
2. Fulmic's Rom (Stock 20c based) Nougat 7.0
3. Hi-Res output was working fine on Android 6.0.1 but not on 7.0. I can select the HiRes output for AUX but music will start playing using OpenSL output. I can switch ON/OFF AUX in HiRes while the music is playing and a message saying it failed will be displayed.
