What do you mean by “so that everything is using the arc connection”? Most TV’s only have one HDMI-ARC and the Beam needs it.
Or is this a case of one HDMI slot interfering with another?
Disconnect everything and redo the TV Setup process in the Sonos app. When the app instructs you to, connect the Beam to the TV’s HDMI ARC port. After the Beam has been successfully connected, connect the other devices to the TV in any order.
So items not connected to the HDMI on the tv with the arc will still get funneled to the sonos beam via the arc connection it is on?

The Beam will be connected to the HDMI ARC port on the TV. The other media devices will connect to the TV’s other HDMI ports and send audio though the TV out to the HDMI ARC port to the Beam.
