Hi. Happy Sonos Beam Gen 2 owner, and just this week, I upgraded the Sony Bravia family tv to a bigger size. I tried to set up the Beam as normal to connect. Sony Bravia sync (CEC) was on, eARC mode was set to “off”, and the TV actually connected to the Beam briefly, sound coming through the Beam for about 3 seconds before reverting back to the TV speaker audio. “Digital Output” on tv audio settings went from white to grey and became unselectable. I tried this 4/5 times with the same result. The Beam connected but didn’t remain so, and the sound defaulted back to the TV speakers.
I will add that I unplugged two other hdmi connected inputs so it didn’t conflict.
Highly frustrating knowing the Beam works, but something is throwing the connection out. I’d appreciate any advice that you may have to try fix this problem in a different way.
