Hi Rehab,

I am on Mojave 10.14.3

Through your guides managed to get

the following working:
- DSDT error free + Patched
- disabled Discrete IGPU native power management
- Sleep/wake/lid closure
- Brightness control
- USB ports limitation
- wifi + BT
- HDMI sound on HDAU

Not Working:
Sound on HDEF with device ID pci8086,8c20, although device is listed in PCI, system report as attached. Tried to patch through AppleHDApatcher, no hope.

Could you help me please.

Thanks

Note: In case you're wondering, Skylake (and Kaby Lake, and Coffee Lake) are similar to HD3000/HD4000 in that the HDMI/DP codec is on HDEF (typically HDAS in PC DSDT, renamed to HDEF for OS X) instead on a separate device HDAU.
Hello. Do I not need to rename B0D4 to HDAU or inject information to it if I have a Kaby Lake R system? More like can anyone tell me what B0D4 does if HDEF has the codec for HDMI on Sky Lake+? No use for it in macOS?

Didn't work for me. My Lenovo laptop HD5500, hdmi audio sometimes works. When it works, ioregistryexplorer shows connector type 00080000. But when it not works ioregistryexplorer shows connector type 00040000. Have checked all requirement , layout-id in HDEF HDAU, "hda-gfx" = "onboard-1". Can not change connector-type to 00080000

Hello, I need your help!
My laptop keep rebooting if I connect display through HDMI port. I'm using Clover config that you provided (for HD620 not spoofed). I've tried to uncomment everything that is described in this topic, alsdo tried FakePCIID kext - nothing helps..

Hi guys, I'm trying to setup HDMI audio on my LG Gram 17 (Whiskey Lake i7-8565U, UHD620, CX8200). I followed the guide in the 1-st post in this thread. check-list seems to be OK, I have no problems with video hdmi output and Intel HD audio also is working fine. But I see no hdmi device in the list of output audio devices. Can you help, please. gen_debug output file is attached
Thank you.

I have asus rog gl703vd. In ioreg/IGPU, I can't see anything then AppleIntelFramebuffer@0 (my internal display). I tried to delete the "#" of all "framebuffer-conX-enable=1" and " framebuffer-conX-pipe=<12 00 00 00>", but when I am connecting HDMI, the laptop restarts. I tried also to delete the "#" of all "framebuffer-conX-type". Could someone help me?
