I have setup several web radio stations on my Fritz router, which presents them as a UPNP stream on my fixed and WiFi networks. The stations are found automatically by my Samsung TV, laptop, and on my phone using VLC, all without login. However my Sonos system does not display them and I cannot “force” it to find them. (The Sonos system accesses the tracks on the Fritz NAS after adding as a Media library, so it can reach the router fine.)
I am in the ridiculous situation of having to play the Web Radio stations on my TV, which then sends them into my Arc and from then I can stream across the other Sonos devices. Does anyone have any advice on how to get my Sonos system to pick up the UPNP Web Radio streams automatically, like my other devices do?
