i tried but have no HDMI or DP to test :(
Duno it working or not?
as u can see my HDAU is PciRoot(0x0)/Pci(0x3,0x0), not PciRoot(0x0)/Pci(0x03,0x0)
You cannot expect it to work as you have not injected hda-gfx property on PciRoot(0)/Pci(0x1b,0) which is required for systems up to Broadwell.

Secondly, you do not have the connectors patched yet. See Connectors patching for more information.

STEP 5: Inject Property


The next step is to inject hda-gfx property to IGPU. To inject the hda-gfx property, follow the steps below.

1. Mount your ESP
2. Open your config.plist
3. Depending on the bootloader you use, add the following properties (see notes) to your config.plist under Devices>Properties (for Clover) and DeviceProperties (for OpenCore)

DevicesKeyValueTypeNotes
PciRoot(0x0)/Pci(0x2,0x0)hda-gfxonboard-1STRING
  • Sets hda-gfx to onboard-1 on IGPU.
  • This property provides digital audio over HDMI/DP/Type-C and can also fix crash issues when Hot plugging.
  • Required for all IGPU.
PciRoot(0)/Pci(0x1b,0)hda-gfxonboard-1STRING
  • Sets hda-gfx to onboard-1 on HDEF.
  • Required for up to Broadwell.
PciRoot(0)/Pci(0x03,0)hda-gfxonboard-1STRING
  • Sets hda-gfx to onboard-1 on HDAU.
  • Required for Haswell and Broadwell only.
PciRoot(0)/Pci(0x1f,3)hda-gfxonboard-1STRING
  • Sets hda-gfx to onboard-1 on HDEF.
  • Required for up to Skylake and later.

4. Save your config.plist
which is hda-gfx i missing in case?

thank, but if just show when devices plugin so i cant test now, maybe in feature
Unfortunately, it doesn't work like that. To enable IGPU HDMI/DP Audio, you need to have a HDMI/DP Device.
btw, i have success enable extmic for my hackintosh \m/
Great.
