When had whole system set up, for some reason this Arc wouldnt recognize the two symfonisk (nor would they recognize each other as possible stereo pairs).. so i started totally fresh factory restart, only these three speakers, still nothing, and i can’t figure it out. I do have a unifi set up which i’ve read has issues, but I have an arc with two symfonisk bookshelf in another room and it works fine. 

Only thing weird I notice is in my routers client list i see the frame speaker called a Play 5, and the bookshelf shows as an Ikea manufacturer rather than Sonos. is there something beyond a factory reset?

Thanks
