Now I'm using Poweramp V3 with aptx-HD(Bluetooth) output like below.
"Smartphone (aptx-HD is activated) -> Astell&Kern AK XB10 aptx-HD Receiver -> AUX -> Car (Audi A6)"
But I cannot understand how to set HI-res output setting in my case.
Setting -> Audio Engine -> Output -> Hi-Res Output (Experimental)
and then there is only two kinds output option (Wired Headset/AUX and USB DAC) and I cannot find Bluetooth option.
Please let me know how can I use Hi-Res Output through aptx-HD(Bluetooth)
