A:Answer Hi, Steve! Your Klipsch Soundbar will need to be connected to your Roku TV via HDMI and will need to support HDMI-CEC and ARC. CEC, or Consumer Electronics Control, allows commands to be shared between devices over the same HDMI connection as audio and video, letting you control common functions of different devices without having to juggle remotes. ARC, or Audio Return Channel, lets your TV send audio to an external audio device. In order to use these HDMI features they need to be enabled on your Roku TV. To enable HDMI-CEC on your Roku TV follow these steps. Start by pressing the Home button on your Roku remote > select settings > select system > select control other devices (CEC) > highlight system audio control > Check the box to enable System audio control > Highlight 1-touch play > Check the box to enable 1-touch play. Using those steps you have now enabled HDMI-CEC on your Roku TV. To enable HDMI-ARC on your Roku TV you'll start by performing the same Roku TV CEC steps 1 through 4 > Scroll up or down and highlight ARC > Check the box to enable ARC. Using these steps you've now enabled HDMI-ARC on your Roku TV.
