It seems odd that it's still playing HDMI audio when the audio input has been reassigned. I would start by disconnecting the optical from the Denon and look to see if there is actually light coming through the cable from the U7. Next I would double check on the Denon input assignment that the correct optical is assigned (the video shows 2 optical inputs) and that no other analog signals are also assigned to AUX as that may override the optical depending on how it handles multiple audio assignments.
Beyond all that you could try assigning the optical to TV Audio as it shows in the video with no HDMI assigned (just "X" for the HDMI column) and see if you can even get just audio from that input when there is no video playing. If you still cannot get audio on an audio only input then I'd say you're not getting any output from the U7 for some reason.

HDMI is a digital signal so it's not going to be a "bad" connection. My guess would be the volume on the laptop was turned down? Did you try setting the Windows volume to 100%?
Other than that you'd have to look at your receiver to see what kind of audio you are getting. They usually have some indication if you are getting surround, dts, stereo, or whatever.
