1. ZTE Axon 7 (A2017G)
2. Android 7.1.1 (Stock ZTE MiFavor 4.2 - A2017GV1.2.0B06)
3. AKM AK4490EN built-in DAC
Edit: Although in 704 the high-res output plugin is present, variant correlated is "Snapdragon 24-bit PCM" instead of the AKM DAC. And it wouldn't go active anyways, as an error is prompted: "Failed: Poweram Hi-Res Exp Output; Using default output."
Thank you!
