...getting full surround sound? My surround sound system is the Sony DAV-DZ111, my xbox 360 is one of the new ones with the HDMI cable socket, and my TV is a fancy new HD TV. At the moment my surround sound is directly plugged into my Xbox 360 using the red and white wires, which only gives boring stereo surround sound. And my surround sound doesn't have an optical input/output, which the xbox demands you use. Could i do something to make my xbox use surround sound? e.g. do something with a HDMI cable.
