Just for making a test I installed LUMÏN application on my HTC smartphone. Well it has taken quite a long time to charge all the albums from LIGHTNINGSERVER to the music library. Then I have chosen the LUMÏN for the music playback. I choose an album and the ARIES G1 began to play (the choosen album is an MQA file and the DAC indicates the blue MQA sign).
I don’t understand why it doesn’t work in your configuration.
