Hi Frank, Since the HW-T450 does not have an HDMI port, audio connection via optical cable or Bluetooth are your solutions. If your TV does not support Bluetooth, please check out HDMI to Optical converters at Best Buy such as: https://www.bestbuy.com/site/insignia-hdmi-audio-extractor-black/6324750.p?skuId=6324750 ^Patty
