I’m sorry, @volumio,
But I’m going to have to disturb the All-Knowing-One 
We’ve given up…
1: Is it even possible to get an MQA-signal from Volumio and Tidal, when sent from the RPi via Toslink?
2: If yes, what needs to be done? 
Or is Havel mistaken, when he says in the other post, that he made it work?
Sorry to disturb…
