Hello,
I had problems with my Sonos system so I reset the speakers, deleted the Sonos app and reinstalled it. I have added my Play 5 gen 2, my Sub and my playbar and it works fine. What does not work anymore is that it is not possible to adjust the volume on the playbar with the TV's remote control. It has always worked before. Playbar and TV are connected with optical audio cable. It works to regulate the volume with the Sonos app on the phone, but it is far too cumbersome. Can someone help me? Best / Frederick
