I was given a sony bravia 5.1 audio system that has a built in cd/dvd, receiver, and Ipod dock. I am wanting to hook it up as the audio source for a muti-room stereo system. Through the Sony menu I was able to knock the settings down to 2.1 (sub as a different channel) but not simple stereo. Is there a way of converting (or wiring) that to stereo so I can send the audio signal (bass and all) to my right & left speakers?
