Hi guys. I was unsure if this is supposed to go here or in the Receivers section so please excuse me if I am wrong. I recently bought an xbox and have the audio hooked up to my Kenwood VR-506 "CD/DVD" input via its Digital optical input. My problem is I can not get 5.1 out of it. I have the xbox set to Dolby Digital and on the receiver it is showing that all 6 speakers are selected however sound is only coming out of the front ones. Also on the receiver it says Downmix Stereo" and it indicates that Dolby Digital is selected. I have check the Kenwood website and my manuals but they are not of any help. Do you guys have any ideas?
