This is my fourth build. The first 2 builds involved with 4th Gen CPUs and motherboards. I managed after a lot of trial and error to get get everything working well. I tried with a 6th Gen G4400 but it was only a very limited success - no HDMI, graphics accelerate and only low resolution - and I am considering upgrading the CPU to a i3-7100. This is my first build with a i7 7th Gen CPU. After spending days trying everything I could find on the forum, I managed to get a very useful system. The one main outstanding issue is to get the HDMI audio output (the sound with Voodoo get sound through the headphone port and although it says it has HDMI output - this part dos not work). I have attached the EFI file (less the non essential items). Any assistance would be greatly appreciate. Thank you in advance.
