[_Spook_]

So, my tests show:

On the NUC6i5SYK
#1005x sound 4.8 final no 4k patch
#1003x no sound 4.8 final 4k patch
#0926x no sound 4.8 rc8 4k patch
#0917l no sound 4.8 rc6 4k patch

The tests I did before with the #0917 builds was on NUC6i7KYK that has some other hardware components. I will test on that also.

EDIT:
On the NUC6i7KYK (Adjust display refreshrate: off, or else no video or sound)
#1005x sound 4.8 final no 4k patch
#1003x sound 4.8 final 4k patch
#0926x sound 4.8 rc8 4k patch
#0917l sound 4.8 rc6 4k patch

So it behaves different on different hardware...

EDIT2:
Just wanted to add that my setup it 4k all the way. So the 4k patch should work on my setup.
