As much as I bust your chops, I have never been on the "how does Ernie make money" bandwagon, but I have to seriously ask it here. How?

90 minutes to take a receiver out and put it back in just to add one device? 90 MINUTES? I have been in some of the most nightmarish takeover jobs with a mountain of equipment piled on top of one another with seemingly no way to get behind them and still get in and out in maybe ten minutes at most. 90 MINUTES?

Why would you add an HDMI audio extractor when you have a Denon receiver (which miraculously is missing the model number in this post) that surely has at least one optical input. I mean, it is possible that all optical inputs are being used, no way to tell with the limited info provided. The Roku 4, definitely has an optical output. Feed your HDMI to the TV (that miraculously is missing the model number in this post) and you are done. It OFTEN seems like you over complicate things just for the sake of over complicating things.
