I’ve had my C8 for a few months and tried playing a DVD. The picture was displayed but there was no audio. To trouble shoot I took the DVD player out of the console and hooked it up directly to each of the HDMI ports. They all carried the video signal but none carried audio. To eliminate the DVD player and cable as the problem, I connected them to another TV and everything worked perfectly. I plugged my cable box into each of the HDMI ports and they all displayed the cable audio/video. This is the simplest setup possible; working DVD player, working HDMI cable and a working C8. All the inputs are active except when playing from my Blu-ray. I don’t see any fixes in the menu. Any ideas?
