Oh, i didn't known that - i will check it up.
Definitely strange, as when the output is on an another device, or monitor the its working...
@Edo, i am not using any NVME fix. I didn't really measure it , but from the OpenCORE selection to OSX login screen it takes about 5 seconds. Its not blazing fast but faster than my MacbookPro :D

@littlejon, This is my first OpenCORE install. The documentation is not 100% clear and sometimes confusing, but after a few reads i could manage to do it.
I had a Clover install on this PC before this, with 10.15.1 but the audio was buggy with VoodooHDA and the whole pc could froze sometimes. Now these issues are gone.
Overall the native wifi card helps a lot ;)

The clover used npci=0x2000, now i am using 3000. There is no real reason, it would work with 2000 too :)
@littlejon, i used the vanilla guide, but i struggled with the ACPI part. For that, I found this docs: https://khronokernel.github.io/Getting ... With-ACPI/ [its in the guide too but pretty hidden]. It not straightforward, but if you read the whole doc, then you can figure it out.

If you still cant do it, feel free to ping me :)

I fixed my microphone..

I am using an U-PHORIA UMC22, with a condenser mic with just the usb power. My issue was that if the input and output was this device, then it doesnt worked, but if its only one of them then it was fine.
Today i started using an AMD USB Power from SSDT-EC-USBX-AMD and its working now :)

TLDR: you wont get 48V without proper usb voltage ¯\_(ツ)_/¯
please give me your EFI folder download link ? thank
