Could you describe your HDMI cabling please?
If it's NUC -> receiver -> TV, then your new receiver might block (don't update) HDMI communication after suspend.
Yes, the cabling is as you show. My 2009 Yamaha Receiver did not have this problem. My brand new 2019 Yamaha Receiver (same basic specs) has this problem. It's definitely an HDMI issue but I'm clueless as to how to fix it. For the meantime, I will reboot my NUC every time I use it.
