Hello,
I am having a HP Pavilion 15 n series. I am not able to get HDMI working in my lap. When I plug in HDMI Cable, Os X Freezes and restarts.
I am having Intel HD 4400 haswell graphics with Intel 4200U CPU.
I have attached my IOREG also.
I did a rename of B0D3 to HDAU, as mentioned here and injected had-gfx into HDAU device.

HDMI-audio on Haswell has several requirements:
- the device at address 0x00030000, usually called B0D3, must be renamed to HDAU
- the resulting HDAU device must be recognized by AppleHDAController (config.plist patches required if not natively recognized... or you can use FakePCIID_Intel_HDMI_Audio.kext)
- your framebuffer must be patched for HDMI-audio (there are patches in my default config.plist (disabled) files: https://github.com/RehabMan/OS-X-Clover-Laptop-Config). It is trial/error to determine which port your HDMI is connected (actually, they are positional and you can tell by looking at ioreg).
- patched AppleHDA is required (sometimes VoodooHDA works, but my experience has been not good)
- you have to inject "hda-gfx"="onboard-1" for IGPU/HDEF/HDAU objects. This is usually done with DSDT/SSDT edits (_DSM methods)
