I see a number of suggestions here for alternatives to Sonos but I'm not sure they meet the requirements or expectations of what I have for Sonos. I basically want anyone who is on my network to be able to use the music services that I have configured on my Sonos and queue music or set regions or whatever. Ideally this would be mostly unsecured but some light security would be fine -- I basically don't want it to be complicated. The wifi streaming (as opposed to AirPlay or Casting or Bluetooth) is so that once I start the music playing I no longer have to deal with any continuity of the system I used to trigger the music. The app changes have unfortunately transformed my Sonos setup into a mostly useless collection; I can still get it to work but it's so cumbersome and the search and playback functions are so broken that half the time it doesn't do what I want. Are there any real alternatives? Homepods and wiim don't appear to meet these criteria -- is there anything out there that is actually a good Sonos replacement?
