AMD motherboard? HDMIAudio.kext is the best bet. I tried all of the DSDT, HDA patches, none of them work.


If video works with default Radeonframebuffer, HDMIAudio.kext might work.

Need to set fakeID 0x68181002 and set Radeonframebuffer?

Set GraphicsEnabler to No

if you use Enoch.  Likewise with Clover.

 

I don't know if you need to fake pci id.  People say 270x works out of the box, http://www.insanelym...0103/?p=2126955

Attach copy.zip

In the zip there are IORegistry copy and the config.plist file

IORegistry copy and the config.plist file

ssdt is working. edit: not working, see Post #27

Two choices (select one choice, remove before trying other choice):

1. remove config.plist/Graphics/FBName/Futomaki, save, restart

2. edit Futomaki famebuffer per this guide Case_Studies]_AMD-HD7xxx_HDMI_Audio_v3.pdf.zip (try Dashmaki or adapt guide to Futomaki, steps are the same), save, restart

Update: ssdt is not working, remove SSDT-HDMI-AMD-PEG0.aml and install attached.

For Choice 1, yes.

Restart and reply with new IOReg and config.plist
