Beam 2 no longer works with Android TV

I’d try removing the Bluetooth headphones connection first, followed by a power cycle ( unplugging from the wall for two minutes) of both the TV set and the Beam, and when the TV set comes back up, I’d make sure that the Beam is connected to the ARC labeled HDMI port, by reseating the cable, and that CEC was turned on on the TV’s audio settings. Once the Beam works, I would re-add the Bluetooth headphones.

If that doesn’t work, I would call call Sonos Support directly to discuss it. I would not attempt the Chatbot. 

When you speak directly to the phone folks, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

Thanks, I’ve done numerous power cycles with/without HDMI cable attached (definitely ARC port).
Don’t think Sonos support work on Sundays.
Will try dropping the bluetooth devices.🙅

Thanks again.
I WAS going to say: “...TV menus don’t mention CEC, but it is set (as usual) to play through external system.”
But then I found CEC mentioned under the ‘Inputs’ menu leg. (This menu hasn’t been used in many months - probs since the Beam was set up 1st.)

The ‘allow TV to control HDMI sources’ item was un-checked. I reset it and all is now working.

No idea how that setting had got changed.

Thanks for your help.
