Ok, I've paired up the joey's with the correct hopper's, but now another issue has risen. I have no audio on one joey. What's odd, is when I switch the hdmi's around from the hopper's/joey's to the 16x16 matrix, the joey that had no audio before...NOW has audio, but one of the other boxes will be without audio. I am only using hdmi's from the hopper's/joey's to the matrix and have tried inputs 1-5 and even 11-16 with the same result being one of the boxes will not have audio. Any guesses or solutions? Thank you all very much in advance!
