I'm really hoping someone can help me with a surround sound problem. I have an nsr5101hd receiver, a Vizio e60-c3 television, and a new roku streaming stick, all hooked up with HDMI cables. I can get picture and stereo sound, but I can't get surround sound. I've tried plugging the roku into the TV and the receiver, and neither works. I've also tried connecting the TV and the receiver with an optical cord, still nothing. I've tried switching the receiver to HDMI passthru, and I lose both picture and all sound. My set up hasn't changed for a blu-ray player that was already attached, and that still has surround sound.
Any help someone can offer would be much appreciated.
