I have a Yamaha RX-V383 receiver/amplifier receiving ARC sound input via HDMI from an OLED LG TV. I would like to have the option of having the home theater sound via the ARC connection and at the same time be able to connect two sets of Bluetooth headphones to listen to the sound. Further, I would like to be able to mute the sound to the speakers and keep sound to the two sets of headphones without having to physically plug and unplug anything. I know I can buy a dual channel Bluetooth transmitter for the two headphones, but where does it receive its input to provide the desired versatility described above? Suggestions appreciated. (There appears to be no way to get a signal for the dual channel transmitter from the LG TV without killing the HDMI sound input to the amplifier).
