Have done some research, and apparently need to figure out how to play DSD over PCM (DoP).
I cannot figure out how to do this. Unsure if it is a software setting or an OS setting.
I have a Topping D50s which is capable of playing the files. Have tried Adacious, also the other music players that come packaged with LXLE, but all I am able to get output to the DAC is 44Khz.
