Sorry to hear about the problems you've been having with this setup. Could you let me know the complete model numbers of products involved? Also, based on the Rogers cable box, I assume you're in Canada, correct?
I just recently purchased a Samsung 60" LED SmartTV with a Samsung Surround Air Track speaker system. We hooked everything up, but were missing some HDMI cables. We got those and tried hooking up the sound bar. We put one HDMI in the HDMI out port on the Rogers NextBox to the HDMI in on the subwoofer. Then one in the HDMI out on the subwoofer to the HDMI 1 in on the TV, just like the diagram. Then we got an error message saying that there is no signal for HDMI2 - yet we have it plugged into HDMI1. When we switch to HDMI1, it says it's not connected. We want to use this system to its full capacity yet are perplexed why this isn't working when it's Samsung to Samsung?
