Not sure if this is what you guys are seeing, but I’ve had situations where when I have my Android Plexamp cast to my Sonos system, it often resets the volume of the Sonos speakers to 0; the connection is super squirrelly and I often need to disconnect and reconnect it. I’ve been able to get it to work every time, though, FWIW.
There’s also this long-standing bug with Sonos and Plex which doesn’t really improve the troubleshooting process, where it will pause after 20 seconds of playback.
