OK...it's fixed but with problems
Went over to my friend's apartment yesterday. I had his main problem fix in under 2 seconds. I turned up the volume. Yes, the volume was too low and that was why he couldn't hear anything.
Now, after figuring that out and Comcast was working just fine via HDMI, I reconnected his BR player via HDMI through the the receiver. This is where I ran into problems, new ones for him. The audio worked just fine, but the video signal would not remain intact. It constantly would start playing then search for signal and back an forth. Sounded like some of the hand shake issues I read about. He had 2 HDMI cables and one was worse that the other, but neither got the job done. To get around this, I simply went directly to his TV with HDMI and ran audio via an optic cable (his player did not have a coax digital out). I have to say that the Pioneer 520 manual is one of the poorest written manuals I've read. Maybe because it's an entry level receiver but it seemed to only make sense once you figured it out by yourself.
