I have recently started to listen to Virgin Radio (via TuneIn) on my Sonos One.
If I select Virgin from the Sonos App all works well, but if I ask Alexa to "Play Virgin Radio" it will stutter and not play correctly. Sometimes it will play havoc with the Sonos to the point that I can't stop it (either via the app or Alexa) and have to cycle the power.
Occasionally it tells me there is an "incorrect stream".
If I change the voice service to Google it will play OK.
If I play other stations from TuneIn via Alexa they work OK.
Does Alexa stream things in a different way ?
