I currently have a SONOS Playbar hooked up to my tv and have two built in ceiling speakers that are connected to my SONOS Connect:Amp which is hardwired into my router. I recently noticed that the two ceiling speakers stop playing sounds or music when ever a movie was playing or I had music playing on the Playbar. I tried doing a retune and it always said speakers were missing. I just updated all speakers and app to try and fix the problem. Nothing worked, so I decided to factory reset my Connect:Amp and reset it up as it's own device. Once I did that, I could play music through the speakers so I knew they were still working. I then went to the website: http://######:1400/wiredsat.htm and replaced the # with my Playbars IP code to set up the surround sound. I then selected the Conncet:Amp to set up as my Left and Right surround sound speakers and set their distance away from the tv. Hit complete and was notified that I was all set up. I then went back to the app and retuned the speakers for the new surround sound, and was notifed that "speakers where missing" yet again. I've redone this 3 times with the same result. any advice would be greatly appreciated.
