First of all I have an Arcana in this loop. But everything was working fine until it quit working fine. So today I unplugged Sonos Arc HDMI cable from the TV and the Sonos Arc, unplugged power cables from the wall for the TV & the Sonos Arc. Waited like 5 minutes. Plugged the HDMI back into the Sony Arc port and then the Sonos Arc. Powered up the tv and the Sonos Arc. Sound from TV to Sonos ARC worked. Unplugged the Sonos Arc HDMI from the Sony TV arc port and plugged it back into the Arcana. Went to the Sonos iPhone App, System, Arc + the surround sounds, including Sub, TV Setup, Let’s get your Sonos Arc SL connected to your TV, Connected cable to Sony Arc and sometimes it will go to the next screen but only to give me a failure something like not connected. I’m befuddled. Everything was working and now it’s not.
