I just purchased 2 Play 1's, a Sub and a PlayBase. I have connected the system successfully to my Sony TV, brand new also. Unfortunately, I am not getting Dolby 5.1 surround sound. I verified this on my Sonos App by looking at "Settings" and then "About My Sonos" which shows an "Audio In" note regarding my PlayBase that indicates "Stereo" not "Dolby Digital 5.1". But also the 2 Play 1's are not working. They connected fine, but there is no sound from them. I am not very technical, so cannot really troubleshoot anymore. Diagnostics 7822627 if anyone can help?
