audio works only when connected directly to sound portion of home theater system. In other words, the HD component cable green/red/blue go onto the back of the TV in the Comp 2 area, but if I hook up the red and white audio there is no sound on the Wii. If I hook up the red and white to the back of the sound receiver I get sound but then where do the green/red/blue HD plugs go? The cord isn't set up though so that it can be hooked up to 2 different places. Any ideas? We have a Mitsubishi 55" HD TV and a Yamaha Home theater system. Both are probably about 4-5 years old.
