Hello Marciano !
I am using a NUC7i3DNHE - should be similar to your nuc7i5bnh. Currently I use Milllhouse LE9 #0720, but HD Audio passtrough is not working.
Just for testing I installed WIN10 with latest Driver and officiel LE 8.2.5 - HD Audio passthrough is working fine ...
What do I wrong with the Millhouse release ?
Best regards,
jack_d !
