A:Answer This is not correct! If you use an optical cable and HDMI ARC, you can use a Bluetooth transmitter connected to the optical at the same time that you are connected to HDMI ARC. After initial setup, just don't change audio output from soundbar from HDMI to optical. Leave it alone! I have this setup. Remember to manually change the Dolby Digital output in audio settings to PCM leave Bitstream setting active, and you're good to go.
