Hello Toleda


I have the hackintosh of a friend with this configuration


CPU: i7 3770k
Motherboard: Gigabyte z77x-ud5h rev 1.1
BIOS version: F15Q (last version)
Onboard video: disabled
Discret video: MSI nVidia GTX650 1024 Mb
Bootloader: Clover (last version)
ALC codec: 898
OS: Mavericks 10.9.5


... and I want activate audio HDMI using the graphic card nVidia.


The onboard audio is working using this method

Realtek ALC AppleHDA Audio Patch Methods - select one (requires native S/L/E/AppleHDA.kext)
1. realtekALC/patch in place: script detects the codec and patches the native AppleHDA.kext for ALC onboard audio. Run the same script to restore audio after Software Update.

1. realtekALC/patch in place
   1. Bootloaders: Chimera, Chameleon, Clover
   2. Software Update: run same script after update restart
   3. More Info: toleda/audio_RealtekALC
   4. Installation - realtekALC
      1. Download: (View Raw) audio_realtekALC-110.command.zip
      2. Double click: Downloads/audio_realtekALC-110.command

      4. Confirm Realtek ALC (y/n): (885, 887, 888, 889, 892, 898, 1150 only)
      5. Legacy_v100202 (y/n): (887, 888 only)
      6. Enable HD4600 HDMI audio (y/n): (887, 892, 898, 1150 only)
      7. Verify Patched AppleHDA kext installed
         1. S/L/E/AppleHDA.kext_vx.x-toledaALCxxx
      8. Restart
      9. Verify ALC onboard audio
         1. System Preferences/Sound/Output/select audio device

Could you say the method to follow for enable the HDMI audio using only the video card nVidia?

Thanks in advanced

See Post #1/Part A/HD4000/7series
Download HD4000 pdf and dsdt method pdf
See Note/Note/1. MaciASL/dsdt patches

Support; see Post #1/Problem Reporting

No HDMI audio edits in the attached dsdt.

True, i must have ignored that when I try to compile the DSDT i get:

10396, 6085, Object not found or not accessible from scope (_SB.PCI0.PEG0)

10396, 6116, Forward references from Scope operator not allowed (_SB.PCI0.PEG0)

However PEG0 is present. !?!?!

True

Recommended to apply HDMI audio patches before PJALM.
For your dsdt, edit the AMI-HD4000-AMD-Nvidia-A3 patch:

HD4000/AMI-HD4000-AMD-Nvidia-A3

edit patch #4. add:
                "@4,connector-type", Buffer() { 0x00, 0x08, 0x00, 0x00 },\n
                "@5,connector-type", Buffer() { 0x00, 0x08, 0x00, 0x00 },\n

remove patch #6:
# 6. Insert HDMI audio injection into device HDEF (HD4K HDMI audio - Part 2/2)
into method label _DSM parent_adr 0x001B0000 remove_entry;
into device name_adr 0x001B0000 insert
begin
    Method (_DSM, 4, NotSerialized)\n
    {\n
        If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }\n
        Return (Package()\n
        {\n
                "layout-id", Buffer() { 0x03, 0x00, 0x00, 0x00 },\n
                "PinConfigurations", Buffer(Zero) {},\n
              "hda-gfx", Buffer() { "onboard-1" },\n
        })\n
    }\n
end;

Apply

paste:
into scope label _SB.PCI0.PEG0 set_label begin _SB.PCI0.PEGP end

Apply
Close
Compile

I need a little help with getting the HDMI to work or to let me know that is a lost cause. With a patched AppleHDA and some DSDT patches my HDMI video is working, following the guide results in no audio and a crash when HDMI is connected. I'm attaching files for both states.

1.- Laptop crashes (kernel panic attached screen shoot) when rebooted with HDMI cable or connecting the cable when OS X booted.
No Audio when booting without HDMI cable plugged in.
Audio and HDMI video with patched AppleHDA.kext.
2.- Mac OS X 10.10.4 / Laptop Lenovo Ideapad P580 / BIOS 5ECN96WW(V9.01) White list removed + advanced options enabled / Intel Core i5-3210M / Intel HD 4000
3.- Several the one that worked was this one http://www.insanelymac.com/forum/topic/298663-applehda-for-yosemite/, then I tried some more for the HDMI, the last was this thread.
4.- Attached ioreg files for boot with HDMI patches and with only patched AppleHDA kext.
5.- Attached DPCIManager pic and System Information pic for both instances
6.- Attached modified AppleHDA.kext and clean AppleHDA.kext
7.- None
8.- Using Clover
9.- Attached config.plist, log, DSDT and SSDT.aml for both working and not working

Thanks in advance.

No idea what is causing the panic.
HDMI audio works with the native AppleHDA.kext.
Without a HDMI device connected in IOReg, problem solving is not possible.

I'm attaching a IOReg of my hack with the HDMI connected with the patched AppleHDA, at least this is what I understood from your post. Sound works but no HDMI sound option.
