I am having a very frustrating and mysterious problem. I have a Denon AVR, and I occasionally use Spotify Connect to play music on it. Recently, I have been coming home or waking up to find that my Denon AVR started playing Spotify music by itself.
In each case, the AVR was turned off before I left or went to sleep. The music that is playing is garbage that I would never listen to. Today I turned on the Spotify app on my Mac to see what exactly was playing. It was an album (again, not one that I have ever listened to or would). Although I could see the tracks in my Play Queue, oddly none of them appeared in my History. I wonder if that suggests that the problem is with another account? My wife and son also use Spotify, but do not use Spotify Connect with this speaker.
For now I have disabled the feature on my Denon AVR that allows it to turn on when it is in stand-by mode. But this is clearly a Spotify problem. How can I prevent this from happening? Or at least, how can I see what device is issuing Spotify Connect directives in the middle of the night?
If I am unable to solve this, I plan to get rid of our Spotify Premium family plan. Since Spotify Premium is needed for connect, I think that will fix the problem.
I have found some reports from Sonos users that sound similar... but nothing from Denon users.
