Hi, I use Volumio 3 and I have a premium account. As of today, I am also the proud owner of two Sonos speakers. Of course, the audio output should also be on the speakers.
Unfortunately, volumio does not find a cast. When I click on “Cast”, I get the message “No cast device found” 
The Sonos speakers are registered in the network and have an IP.
Do I need a specific plugin or Tidal access? I have no idea and would be grateful for an answer.
After restarting volumio, the problem was solved 
I get the Sonos speakers displayed as “cast” and wow, it works wonderfully. I’ve been playing with it for three days now and don’t want to miss it. Great 
how does this work? do you have to select or “cast” it everytime you play something, or is it the default output once it is selected? I am thinking about getting some Symfonisk picture frame speakers because of the high WAF ( and they measure reasonable well, especially with PEQ ), but it has to work flawlessly.
