I don't mean just a lightweight plex client, but a headless plex audio sink. Plex supports , "passing" your stream session over to another client on the local network now, I'm not sure what protocol it is exactly but my Tcl Roku tv is compatible with this and its quite handy to be able to queue some stuff up on the mobile app them send it over there to play rather than fumbling with the remote and the handicapped Roku app.
