It's connected via optical cable to my tv. My v6 tivo is connected via hdmi to my hdmi arc 1 socket on my tv. As recommended by my soundbar manufacturer. The Audio setting on my v6 tivo is ticked on dolby digital. Which is what my soundbar is designed for. Anyway I had a chat with one of the guys over the phone at your tv tech team. I mentioned that I'm having an issue with sound on some recordings from sky cinema HD and occasionally film 4 HD. Basically the actors mouths are moving. But no sound. So I stop playback. Then press play again to resolve issue and get sound. The guy mentioned it sounds like theirs a slight compatability issue with my v6 tivo and soundbar. He said it should be fixed with a software update to my v6 tivo over time? Would a fix to this issue be possible?
