I have a question that I'm sure you guys can help me with. Let me see if I can say this without confusing you. I have my HDTV, HD DirecTV receiver, XBox 360, and my DVD player/Sound System. I currently have my HDMI going from my DirecTV receiver to my TV. When I want to play XBox 360, I disconnect the HDMI from my DirecTV receiver and plug it into my XBox 360. Obviously, I am going to get a HDMI switcher. So here is my question . . . If I have a 3-way HDMI switcher and connect the DirecTV receiver, DVD/SoundSystem, and XBox 360, will I not be able to get digital sound to my DVD/Sound System in my games? Will I have to use an optical cable to connect from the XBox 360 to my sound system? Hope that isn't very confusing. Any help is appreciated.
