I have a Sonos Amp connected to a turntable. Sonos One in kitchen. Primary purpose of getting the system was for the ability to listen to records in both spaces. The nice thing is, busy cooking and record ends, quick voice command to go to Spotify playlist.

However, I can't seem to find a voice command to change it back to the line in for source when I want to go back to play a record. Is the only way to change via the app? HUGE flaw in the system if so and should be a developer priority. Quick search shows topics looking for this for over four years.  May even consider returning and building a traditional multiroom system instead.
