Discovery wroteHi Rikardo,
That very long thread didn't tell me anything about Bubble uPnP other than you have successfully enabled it to work with Tidal.
Can you give me a few hints or steps to get me started...?
Thanks,
Trevor
there is nothing to set actually

If you have your RPi with RuneAudio set all you need to do is to download Bubble uPnP from play store, install on your phone or tablet and thats it

In within the app you add Tidal under Cloud services and than select RuneAudio as a renderer
Than you simply browse your Tidal from within Buble uPnP and when you click it plays on your RuneAudio
Thats all
