Just one of my five zones needs Sonos wireless comms, the rest are all ethernet wired back to the router, This one zone is an Echo Show wired to the line in of a Connect. The Connect line in is set up to autoplay to a Play 1 pair + Sub. All zones are set up to use Sonos net.
When all zones but the referred one are powered off, the play 1 pair+ Sub will still play music that the Echo sends to the Connect. This must be via an independent WiFi comms set up from the Connect to Play 1 pair + Sub. The question I have is if running an easily run ethernet wire from the Connect to one or both play 1 units will enhance music play stability or hinder it.
To eliminate some occasional stutter I have set the delay to the max of 2000 ms, but I cannot be sure if that is in the wireless stream to the Show, or downstream of it in the Sonos components.
