A:AnswerTry the VGA cable and then toggle between Modes using the small Polk remote to see if you can get sound. The optical cable didn't work for us regardless of the Mode selected.
A:AnswerNo, it does not. While it does have an audio return channel (ARC) via the hdmi input, it does not support hdcp 2.2. You will only be able to watch dvds and non-protected audio content such as the other language audio tracks on a blu-ray.
A:AnswerYou can program your cable remote to control the sounder depending on your cable provider. When I turn my tv off and on the sound bar does the same.
