Newbie here :b I'm trying to set up a Denon avr1604 Receiver for the first time. My problem is I can only get sound in Direct and Stereo mode, and only from the two front speakers (from an analog signal) I cannot seem to get any signal to the Surround/Sub speakers. Also, I cannot get sounds from the Test Tones either. Am I missing something in the setup/configurations? Even when I use a digital signal the receiver picks it the digital signal, but still there is no sound. Any ideas?
