GUIDE How to Enable Intel IGPU HDMI/DP Audio on macOS

[EliteMacx86]

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.

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.

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)

Devices	Key	Value	Type	Notes
PciRoot(0x0)/Pci(0x2,0x0)	hda-gfx	onboard-1	STRING	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-gfx	onboard-1	STRING	Sets hda-gfx to onboard-1 on HDEF. Required for up to Broadwell.
PciRoot(0)/Pci(0x03,0)	hda-gfx	onboard-1	STRING	Sets hda-gfx to onboard-1 on HDAU. Required for Haswell and Broadwell only.
PciRoot(0)/Pci(0x1f,3)	hda-gfx	onboard-1	STRING	Sets hda-gfx to onboard-1 on HDEF. Required for up to Skylake and later.

4. Save your config.plist

Unfortunately, it doesn't work like that. To enable IGPU HDMI/DP Audio, you need to have a HDMI/DP Device.

Great.
