I find it is impossible in practice to use the Beam (Gen 1) connected to my recently purchased LG OLED TV through the ARC socket.

If I want to switch to Bluetooth headphones, the connection lasts for a few seconds before the Beam snatches it back. If, on the other hand, I connect my DVD player via HDMI, the TV tells me that I cannot use the ARC connection. 

The answer has been to use the optical out connection and everything seems to work perfectly. I can leave them all connected and they function when required. However, I obviously lose some functionality although I have been able to make the volume controllable by the LG remote. 

Do other people have the same experience? Who do I “blame” for this? Is it something about the Beam or is it that LG have not developed an ARC that functions with all possible connected equipment?
