You will get better audio quality if you plug the soundbar into HDMI 3 (ARC). Plug the DirecTV into any other open HDMI port. If you have gotten the newest updates for the TV, it may be able to recognize the headphones and send sound to it wirelessly by Bluetooth. After the update, go to Settings, Scroll down to Bluetooth settings, turn on Bluetooth, and then add your device. I know it works perfectly for my Sony MDR-1000X phones, and many others.
