I use shairplay[0] to stream from an iOS/macOS device, and Mopidy[1] with the Iris UI[2] to play server-side from your music collection, Spotify, or other internet radio.
My "speakers" are cheapo Bluetooth speakers with a raspberry pi attached to the back. Works beautifully and reliably. If the old Sonos devices have line in, maybe this is a way to continue using them?
