My wife loves to listen to TV episodes. Please allow audio only playback of video files via sonos (Transcoded?).
That’s a Sonos issue, not Plex. I know where you’re coming from though. I was really disappointed by the extremely restrictive the Sonos ecosystem is; Even more shocked at how awfully the Sonos Controller is!
Unfortunately, you need to buy one of their products that supports line-in (Play5, Playbar, Playbase, Connect) if you want to listen to video streams.
I ended up connecting a Chromecast Audio to my Play:5 so all my devices can cast to Sonos now.
Why is this a Sonos issue?
