We play music and kids’ stories served from a windows server. This worked fine for years. After disabling SMB1 because it was 2020 and failing to get the http service to work (with or without firewall) I set up windows media streaming over what looks like RTSP.
We use the Sonos Android app (12.2.2), and also the Windows one, less often. Navigating the metadata works as expected, but this is not generally how we use the app. It isn’t really feasible to browse, or even search, tens of thousands of objects, made up of four or five distinct collections, as a flat list. The way to do that is to use folders. But navigating by folder does not work as expected: the app browses and finds the content, but it does not treat the folder as a potential playlist. In contrast with other sources (I’m thinking SMB folders, Spotify, Amazon) it does not associate play/add functionality with the list it has found. There aren’t any buttons. Click on a track and it dutifully plays that track and then stops. It lists all tracks, so it recognizes them as an array, but it will not transfer that array to a playlist.
The ask: how do I play RTSP folders?
