I have a Sonos system around my house and a Connect amp into which I have a CD player and wired speakers connected directly. It used to work but now no longer outputs anything. The Connect does not show up on my Sonos app, but when I add it in Settings "Add a player or Boost" it says it sees the Connect Amp and does the whole connection sequence no problem, saying it is connected. But it is not. I have re-connected it several times, rebooted etc etc and obviously have turned the volume up on the Connect itself. Any ideas??
