My cable box is connected to TV through HDMI ARC. I want to connect my soundbar. The only other HDMI on TV is not ARC. Do I just use the optical connector or do I need both optical and HDMI connectors. Will I have to switch back and forth between HDMI and Roku when I use TV
What does the cable box need with a hdmi-arc input that a regular hdmi won't work for it? Put the cable on the just hdmi input, use hdmi-arc for the soundbar.
