Actually not the output quality we're talking about here (fyi, I already set those quality to either extreme or hifi), it is the music that send to the USB DAC (in my case, it is Mojo), it always up-sampling to 192khz (it shows "Red" colour). However, there is no problem using the Onkyo default player (the Mojo will change colour according to the file sampling rate).
From what I understand, those apps (Tidal or Spotify) will send the file via Android default which will upsampling to 192khz. However, since the Onkyo player have its own USB driver (or design?), it'll not follows android default.
Now, my question is it possible to prevent this default up-sampling or hardcode it to maybe 44.1khz (since this is the loose less rate for high quality Tidal/Spotify). The SQ is quite bad when android up-sampling to 192khz when using those apps to play music (it is worst than listening directly via HO).
