[Guide] Intel IGPU HDMI/DP audio (all Sandy Bridge -> Kaby Lake [and likely later])

[RehabMan]

can you remember sir , yesterday you confirmed i should 0105 port

Please read post #1, "Problem Reporting".

Carefully.

Problems I can see just from ioreg:
- layout-id mismatch between HDEF and HDAU
- neither framebuffer connector is patched for HDMI

 

[mindit]

sorry

 

[RehabMan]

sorry

It confirms what I see in ioreg.
- 0105 patch is disabled
- wrong layout-id on HDAU in SSDT-4:

SPEEDY-OSX:patched RehabMan$ grep -A 4 layout-id *.dsl
DSDT.dsl:                    "layout-id",
DSDT.dsl-                    Buffer (0x04)
DSDT.dsl-                    {
DSDT.dsl-                         0x03, 0x00, 0x00, 0x00                       
DSDT.dsl-                    },
--
SSDT-4.dsl:                    "layout-id",
SSDT-4.dsl-                    Buffer (0x04)
SSDT-4.dsl-                    {
SSDT-4.dsl-                         0x0C, 0x00, 0x00, 0x00                       
SSDT-4.dsl-                    },

Also to note: The files in ACPI/patched were not compiled with the ACPI 6.1 compiler as linked from my guide (my version MaciASL/iasl).

so should i patch native files again with ACPI 6.1 ?
thank you very much for looking my files and helping me ,
At this point i was so dispersed

Make sure you use the same layout-id on HDAU as for HDEF (3).

Don't expect disabled patches to have an effect. Patches which you'd like to use must be enabled by setting Disabled=false.

 

[mindit]

yes i'll try inn this weekend thanks
but even though i enabled by now still kp?

KP expected with incorrect layout-id on HDAU.

 

[mindit]

but with all patches enabled it works ,

HDMI audio not expected to work without the correct layout-id. But of course, you need the HDMI patch for 0105 as that is where your HDMI connector is.

I applied the necessary patches and I checked in IOREG. When I plug in the TV, it shows in Output; but when I select the TV, the volume control greyed out. It shows the picture okay but no sound. Kindly advise. Thanks.
