I have had my Onkyo TX-SR602 for a long time now. I have set it up in 5.1 configuration. I know that my speakers work. When I use the supplied microphone, all speakers can be heard during the autobalancing. However, my rear surround speakers are NEVER heard after that. None of my movies (DVD) are playing with the rear speakers. Also, when I listen to CD music, I would love all speakers to be working...What am I missing, this just doesn't seem to be right.
