Hello,

I got since 2 days a strange error on my Ubuntu Mopidy+Snapcast working well before :

- playback fails ONLY with spotify
- I fixed a month ago the authentification issues , which worked well since : [Spotify disabled username/password authentication · Issue #394 · mopidy/mopidy-spotify · GitHub](https://github.com/mopidy/mopidy-spotify/issues/394) and have no Bad Credentials in my logs
- I use a standard output conf working well for all other streams `output=audioresample ! audioconvert ! audio/x-raw,rate=48000,channels=2,format=S16LE ! wavenc ! filesink location=/tmp/snapfifo`

Does anybody encounter the same problem or have a potential solution ?
