I already run that file and mount the EFI partition, but it shows this error message.

Drag the script file into a terminal window then press return. Don't double click the script.

Here's is a copy of SSDT-10 table where device HDAU was patched with the following XDSM method:

           Method (XDSM, 4, NotSerialized)
           {
                If (LEqual (Arg2, Zero))
                {
                    Return (Buffer (One)
                    {
                         0x03                                           
                    })
                }

                Return (Package (0x02)
                {
                    "hda-gfx", 
                    Buffer (0x0A)
                    {
                        "onboard-1"
                    }
                })
            }

I also added the desktop HD4600 id injection before the layout-id injection in device IGPU:

           Method (XDSM, 4, NotSerialized)
           {
                If (LEqual (Arg2, Zero))
                {
                    Return (Buffer (One)
                    {
                         0x03                                           
                    })
                }

                Return (Package (0x04)
                {
                    "device-id",
                    Buffer (0x04)
                    {
                        0x12, 0x04, 0x00, 0x00          // Desktop HD4600 id 
                    },
                    
                    "AAPL,ig-platform-id", 
                    Buffer (0x04)
                    {
                         0x06, 0x00, 0x26, 0x0A         // Azul FB #12
                    }, 

                    "hda-gfx", 
                    Buffer (0x0A)
                    {
                        "onboard-1"
                    }
                })
            }

Make sure that you install all necessary Rehabman's FakePCIID kexts:

  • FakePCIID
  • FakePCIID_Intel_HD_Graphics
  • FakePCIID_Intel_HDMI_Audio
 
Finally and as stated previously in post #, you must patch layout 0x0a260006 of your Azul framebuffer kext to set the relevant output port to HDMI type. This is usually done through the following binary patch:
Find:       01050900 00040000 87000000
Replace: 01051200 00080000 87000000
 
Questions:
  1. which audio codec do you have?
  2. do you currently have audio working with patched AppleHDA?
  3. do you currently have HDMI video output working?
  4. which OS X/macOS version do you currently run?

NB: It could help if you posted your system's specifications in signature.

 

1. For the code, should i remove the existing _DSM on my HDAU to that _XDSM code ? In order my device is laptop, not desktop (S451LB series has only HDMI port and there is no VGA port.

 

2. I have installed all 

*see the Screen shot

 

3. For clover patch, i have added that

*see the Screen shot

 

Answered Question : 

1. How to know the audio codec ? Can you tell me ?

2. Yes, my device is ALC233 and already use the patched HDA and all of output and input are working

3. I try it and HDMI worked

4. Version 10.12.6
