Using HDAEnabler to Get HDMI Audio on HD 3000 and HD 4000

[toleda]

On IOReg how I can read that the patch is working or what should I be looking for ?

GFX0@2/hda-gfx injection is missing, attach the Extra file.
IOReg/HDEF/IOHDACodecDevice@1B,3

Finally fixed. I had to patch my DSDT using your patch AMI-HD4000-Laptop_FB_03_A3 But I only used this part and instead of using IGPU, I change it for GFX0 and that did the trick.

# 2. Insert HDMI audio injection into device GFX0 (HD4000 HDMI audio - Part 1/2)
into method label _DSM parent_adr 0x00020000 remove_entry;
into device name_adr 0x00020000 insert
begin
    Method (_DSM, 4, NotSerialized)\n
    {\n
        If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }\n
        Return (Package()\n
        {\n
            "device-id", Buffer() { 0x66, 0x01, 0x00, 0x00 },\n
            "AAPL,ig-platform-id", Buffer() { 0x03, 0x00, 0x66, 0x01 },\n
            "hda-gfx", Buffer() { "onboard-1" },\n
        })\n
    }\n
end;

compiled without errors, and finally hda-gfx is loaded in HDEF and GFX0@2 and HDEF@1B.

Attached is my new IOReg and DSDT. So far everything is working,do you see something wrong ??

Thanks.

Of course, dsdt edits work. Does not resolve the issue of Chimera HD4000 HDMI audio working on my HD4000 and not on your HD4000.

I have tried with two HD TV's and when they are connected the video does work, but none the sound. When I check System Preferences>Sound the Output is still on internal speakers, and never changes to HDMI, like when I plug the headphones.
