Hi foxint,
Can you look at your Debug UI again and confirm that you can see this text:
Build version: janui-20180903-7
It's the 7 that is important.
Can you also confirm that you have followed the instructions here:
runeaudio-0-5-beta-for-all-raspberry-pi-models-t6532-310.html#p26802Can you then copy one or two music files to a usb memory stick and use this for testing. Plug in the usb memory stick and confirm that:
your test music is visible in the library tab – it takes a little while before it appears
you can play this music and it is show as playing in the main player UI
If it is working and you can hear it, great.
Otherwise: Can you explain how you have connected the XLR output connectors on your HiFiBerry DAC to your amplifier?
