So I have been using the free version of Spotify with Sonos for some time, and decided to go for Spotify premium. Before I upgraded I tested that Spotify app as a free user, and was happy with the ability to control/cast to Sonos directly from the app. But after upgrading to premium it started failing. Has anyone experienced something similar?
Controlling Sonos from Spotify:
Shortly after upgrade to a family plan I was no longer able to successfully cast to Sonos, my devices will show up, but there is either just silence (while the app shows it is playing), or simply a failure to connect. After a connection failure the Sonos speaker will (strangely enough) start playing whatever was the last music/service it played. Weird. Sonos devices (Play 1 and Move) will however reliably show up in the connect list.
This behaviour is consistent from both Android app (tested from two devices) and from the PC app. I have removed the Spotify service and reinstalled in the Sonos app several times. Have turned Sonos speakers on/off several times. Have rebooted phones and PC. No improvement.
Controlling Spotify from Sonos:
Works perfectly, always. Simply select a song and play.
Testing with Tidal:
I decided to go for a trial family subscription with Tidal service and tested from Android. This works perfectly so far, Sonos devices show up and I can control them. Based on this I might be forced to go with Tidal. (Although Spotify have better podcast support, which is an advantage)
