Optiplex 3070 i3 9100 Graphic Issue

[lekiu]

i got an 3070 with i3-9100T too. Base Installation (10.14) works, Ethernet is up and running, but i cant get Audio to work and can only boot with "inject intel". I actually have no idea what im doing wrong.

My Settings:
- Clover 5104 installed on system drive (i used the SATA port for testing, and will go later for an dual boot on PCIe SSD)
- installed iMac 19,1, Realtek Ethernet, AppleALC and Core Graphics Fixup on system drive
- also tried to copy newest versions of this files to EFI partition (other folder)
- also tried to use your EFI folder (can´t reach login-screen, reboot loop)

-> do you install/copy these kexts to EFI Folder only?
-> why do i only have an Video Memory of 14MB?
-> what i´m doing wrong with this Audio kext?
-> my display is connected to the DP Port. I ordered the optional HDMI 2.0b port and will post the part number until i got it in my own hands -> will cost around 20 bugs in germany
- Should i instead go to 10.15??

If you a trying to boot with GTX 1070 it unsupported in both Mojave and Catalina. Either replace with compatible card or remove and use iGPU.

The last one you could set is CFG Lock to Disabled.

Hi, I just using Opencore 0.5.9 installed Catalina 10.15.5, all works, Only there are no sound, I using alcid=11 in the boot-argu, and also I have tried all the possible of Realtek ALC3234(actually ALC255): layout 3, 11, 13, 15, 17, 18, 21, 27, 28, 30, 31, 99. No one can make the Micro PC have a sound. May it need to add in the Device-Properties-PciRoot(0x0)/Pci(0x1F,0x3)--Layout-id add B0000000? Can anyone help me with it? Thanks!

@coralding Are you connecting with DP or HDMI?

Using Display Port，Now Catalina 10.15.5 has a issue of HDMI out-Monitor.
Here is my EFI, wish some body can help to deal with the Sound Layout ID.
Use your own SMBIOS ID, your own WiFi-SSDT and Password in itlwm.kext‘s info.Plist
Thanks！
