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.<br>
