rx570 proxmox gpu hdmi audio pass through

[William C]

Hello

 

I hope this is the right forum to post this

 

I have successfully set up Hacintosh the old way with Opencore which I use day to day and love ❤️ ❤️ 

 

I want to set up a Hacintosh the new way with proxmox and single gpu pass through but am getting stuck with hdmi audio not working 

 

i have a gigabyte a320m motherboard , amd ryzen 7 2700 8 core cpu, rx570 8gb graphics

 

I installed a Linux virtual machine inside box box to check that the passthrough is working correctly also for audio and it is.

 

i’ve tried many things.  Far as I know I have correctly downloaded my DSDT and created SSDTs, i’ve set layout ID as 11 and also tried other numbers. i’ve tried adding the PCI device into my config.plist.  I tried getting the on-board sound working and this wasn’t working either.  Sounds works for USB audio Devices.

 

i’m fairly technical and experienced  but I am being stretched my limits when talking of pci buses and acpi tables etc
