I would like to verify some more information about your system configuration so would you please provide your system report information?
How to get it?
System Information: Click Start> Type System Information> Click File> Export> Save File> Attach using Advanced Editor Options.
I forgot to mention that I have tested a 2nd PC on my amp, with an NVidia ti550 video card and it does not have the same problem. That is how I have traced it back to something on the NUC.
Attached is the info from msinfo on my D54250WYK Nuc.
Thanks for looking into this
