For wired 3.5 it works this way:
- DVC works only via Hi-Res output for standard resolution (16bit/48khz)
- Hi-Res sample frequencies (>48khz) works via Hi-Res output, but without DVC
- normal outputs DVC is completely broken in ROM - makes normal outputs not usable on Samsung Pie variant (actually this is tested by Google Compatibility tests, so that's weird)  Bluetooth/USB: it works fine with Hi-Res sample frequencies (>48khz) and DVC. Basically this means you always use Hi-Res output plugin in Poweramp, it just plays standard resolution (with DVC) or Hi-Res (with DVC for BT/USB, no DVC for wired 3.5).
