How do I get sound from my tv to my new sound bar which has a HDMI ARC INPORT AND A HDMI REGULAR INPUT? I can only get sound via my cable box using the optical port to the optical port of the soundbar leaving no sound if I want to use the apps installed in my TV or sound from a streaming device as in Fire or Apple TV and no my tv has no optical port just 3 HDMI PORTS AND AV
