Question about FiiO K5 Pro ESS

This is not a question of Apple Music. The few things (e.g. Nutcracker, Tschaikowsky) that I have tried work, but you have to make a few climate changes in the audio/midi setup so that the highres/lossless is also passed on correctly. It does not happen automatically.

I have connected this device with a tablet Samsung (Android), USB cable DAC connected, with program software AIMP and works super, comfortable. With APPLE I can't say, with ANDROID OK. Greetings.
