I have not found anything other than a sound bar since 2001. Some friends of mine from church bought a house recently and they have speakers mounted in the ceiling throughout the house and outside. The previous homeowners left a controller with a large diameter coming from a hole in the small room into the controller and a Sony receiver have HDMI slot but not old enough to be Bluetooth compatible. They simply Want their TV to be able to play on the speakers throughout the house. They just purchased the TV and I checked and it does output internal speakers, internal speakers plus optical, optical, HDMI and, finally, Bluetooth. Is there a simple controller that I can plug those wires into and they can make the TV talk to the controller or whatever the device is, to play the TV throughout the house?
