I have a NUC7I5BNH (Kaby Lake) that I have not experienced these 
issues.  Then again, it is connected to a stereo only TV, not an AV 
receiver, so I do not know if it has any audio pass through issues. Good 
to know.  I do recall updating the BIOS/firmware on the NUC from a USB 
thumb drive and not needing Windows.  I guess the BIOS is different than 
the firmware you are trying to update.
