Can someone explain why on earth HDMI enabled sound systems are run through the satellite box? That connection then only allows me to listen to the "TV" feed and not all that the SmartTV can do. This simply mystifies me since I've spent a couple hundred on a sound system that will only play part of what the TV can play. Why don't they build the sound system to play whatever the TV is displaying?
