Yesterday I just purchased the STR-DH820 receiver. I don't have speakers for it yet, so i set the audio output to tv + amp. My tv is connected to my old Philips home theater in a box via optical cable to Xantech optical to coaxial converter, then through coax cable to my Philips (doesn't have optical input). I have a Panasonic DMP-BD65 blu ray player, PS3, and Wii hooked up to the STR-DH820. The two HDMI connected devices work fine, but the problem is, there is picture, but no audio signal from the Wii, is connected to the SAT/CATV component in and audio in terminals. I set the input mode to analog, and assigned analog to the the input, but whenever I select the input, no sound. Why is this? Any help would be greatly appreciated.
