Nobody@Home: Thank you very much for joining the Intel® NUC communities.
In order to better assist you we just wanted to confirm:
What is the Linux version you are using?
What is the Kernel version you are using?
Any further questions, please let me know.
I use "Archlinux" as the distribution (it has no versioning) and the kernel version 4.9.30, configured and compiled by myself.
BTW: It doesn't matter, which linux (Ubuntu, Redhat, a.s.o.) and which kernel (4.4.x, 4.9.x or 4.12.x) are in use: IT8607E is not supported yet. Without datasheets it's not possible to make a driver!
