Default Help: Digital Optical output making nothing but noise...

I need advice as to why my audio receiver, an RCA RT2770(perfectly capable of 5.1 digital output)only makes loud hissing/popping noise when used in conjunction with my PC via optical 5.1 output or my Xbox 360(same output). I used to own the previous model which was the 2760, the only differences are that the 2760 had usb input and only 1 optical in, the 2770 has no usb and dual optical in. And it worked beautifully. At least till I needed something with 2 optical in's. So I bought the new one, brand new. I thought I had the problem solved when I plugged my blu ray player into the hdmi and used the optical out on my tv for sound, then I realized while playing Star Trek(2009), that something didn't quite sound right. Some frontal sounds were just being "repeated" via the rear satalite speakers. I thought it might have just been the cables(fiber-optic) but they're fine. It can't be the receiver itself can it? It can't be. It has one coaxial input and I've been able to get 5.1 surround via my blu ray player in both PCM and bit-stream. I don't know what else to do at this point, sorry for the long post. ANY help would be greatly appreciated. Thank you.
