I answered a question from reddit but thought it may apply here as well (the solution below also turns my HUB on/off when I turn my TV on/off: I was in the same situation with a Samsung 65" Smart TV. When something doesn't make sense to me I obsess over it. Based on all the reviews on this, I couldn't get over the fact that a company like Klipsch would put HDMI ARC support in their manuals but not actually have it working. ($50 sound bars even support it). After a few days of trying different combinations on inputs and settings, downloading and updating the latest firmware all while contemplating returning the whole system that I got on sale for a fraction of what it normally goes for, I got it to work with just HDMI cables - no optical cables. I have a Samsung Smart TV that comes with a One Connect input box that uses a proprietary cable to run back into the TV. (there are no input signal ports on the tv) How I got it to work: My PS4 and Chromecast is running into the Samsung One Connect HDMI 1 and 2 inputs respectively. I have the Samsung One Connect HDMI 4 port (ARC) running into the Klipsch Hub's HDMI OUT/TV. The TV and Klipsch Hub both have ARC/CEC turned on. Here is the trick, you have to set the Klipsch source to TV. All audio coming from the tv, including smart TV apps, the PS4 and the Chromecast comes out of the Klipsch speakers. I didn't think to try switching the Klipsch source to TV because in my mind TV inputs in the past have always been for coaxial (cable) connections. My only issues now are that I have to change my Samsung input to HDMI 4 if I need to change Klipsch settings. So far, I haven't experienced the other major issue folks were having with speakers dropping out. Hopefully I'll get lucky with that one. The sound that this system puts out is fantastic. It's awesome to hear all the work these composers and sound engineers put into these movies and shows.
