Having trouble with my Hisense Roku TV and pairing it with my Onkyo AV Receiver HT-R393. Tried a digital audio cable and nothing. Tried HDMI cable combinations and nothing. I'm clueless. I swallowed my pride and came here. Anybody give a guy a hand? The only sound I am not getting is the menu and the apps. When I choose my HDMI channel for my Xbox, it works on my surround sound. Just not the menu and apps on the Roku TV.
