I did not configure the iGPU. The iGPU configured me to disconnect the HDMI-cable before booting.
I have used the unified version of the EFI by Pastrychef, which I configured for a specific motherboard's "USB-ports" after his description. Audio is missing, probably I missed something. The HDMI-cable have to be unplugged when booting. My guess, as a total beginner here is that it might be more fruitful for you, to download the unified version of the EFI on page 1.
Are you using HDMI audio or one of the audio jacks from the motherboard?
Are you saying you don't get any video unless you leave your HDMI cable unplugged when booting?
Please post your EFI. I would like to see what changes you've made and if I can help fix any errors.
