Audyssey sound correction window does not appear on Roku TV screen

Hey there! pompanovice​ 

We've checked your concern, and it sounds like this issue might be caused by not setting up the Denon receiver correctly. Also, if you’ve already got everything running through HDMI ARC, there's no need to use the optical cable. For advanced troubleshooting, we would highly suggest reaching out directly to Denon support for help.
