Attach IOReg with working HD520.

My mistake.
Not tested, make bootable backup, remove any existing HDMI audio files, edits, etc. Download v0.21 and run. Reply with Terminal output and IOReg.

thanks you for this new patch. It doesn't work with 1.21.

But I think it's my fault. The first time i sent you an Ioreg, I use wrong injector (1912- Hd515 instead of 1916-HD520). So the patch can't work...

Thank you for you help. (and sorry for the mistake) ioreg_config_chich0n.zip

[toleda]

Big problem; no IOReg/HD515 HDMI codec, not enabled. Verify BIOS setting. ssdt worked, script error fixed, download again and run. Attach IOReg and config.plist

[chich0n]

So I don't understand why my codec seems to be disable; It works fine under windows and HDMI audio is enable in BIOS.

[chich0n]

I send you my IOReg and my config.plist :)

Remove config.plist/ACPI/DSDT/Patches/ (requested above):

1. 10.8+-Rename-GFX02IGPU
2. 10.11+-Rename-HECI2IMEI
3. Fix Skylake audio by renaming HDAS to HDEF Run cloverHDMI DPCIManager shows ALC283 only, no HD515 HDMI audio codec; no HDMI audio,

[chich0n]

I removed config's line : same result, no hdmi codec. It's very strange

Hello Toleda,

Apology if my issue is out of topic here. Nonetheless, this is most related to my issue I can find. I am not getting video to HDMI. My environment is El-Captian 10.11.6 running KabyLake / HD630 It would be appreciated if you can show me direction. Please find the attached onionsjk-ioreg.zip for your reference.

[toleda]

Hardware?? IOReg shows laptop display connected, no HDMI connected. Connect HDMI display, restart, reply with new IOReg.

[jungjinki]

Please find the attached for ioreg-with-HDMI-connected. I reboot with HDMI being connected.

onionsjk-ioreg-with-HDMI-connected.zip

[toleda]

2nd request, what hardware? IOReg does not show a HDMI device connected. System Information/Hardware/Graphics/Displays will not show a HDMI device connected.

[jungjinki]

I think a little bit of history is required at this time.

my notebook is Dell Inspiron 7567 KabyLake CPU running OS El-Capitan 10.11.6. It has two graphic cards 1) Intel HD 630 and 2) nVidia 1050 Ti.

The first issue I faced was "7MB graphics". Graphics is slow and no HDMI video. Some applications I heavily use stop running and my suspicion was graphics.

I have tried nVidia Pascal driver but I couldn't make it. But I managed to get "Intel Uknown 1536MB" using Intel HD option with help of https://www.tonymacx86.com/threads/new-testing-intel-7th-generation-kaby-lake-cpus-200-series-motherboards-in-macos.219877/

Changed items are as below: ___- FackCPUID to 0x0506E3 __ - no acceleration / I don't know how to set __ - Intel HD 530 patch from MultiBeast __ - Intel Graphics ID spoofed to 0x19168086 under /Devices/FakeID/IntelGFX __ - FakePCIID.text and FakePCIID_Intel_HD_Graphics.ktext to /Library/Extensions __ - AddProperty "Skylake Glitch Fix" to Devices/AddProperties/

Now graphics is fast and my application is running normal. Only video to HDMI still not functioning.

Searching Dell Community site to find hardware info for HDMI, I find "Optimus" but sorry I am not so sure it is right name or not. http://en.community.dell.com/support-forums/laptop/f/3519/t/20007601

I hope this to be a help for trouble shooting.

I have a perfectly working notebook Dell Inspiron 7559 Skylake CPU and can get its IOReg which will be useful for troubleshooting. But it will be available on weekend only. Once done I will upload here.

[toleda]

You have enabled Kaby Lake graphics, not Nvidia. macOS does not support Optimus or the device that switches graphics between Intel and Nvidia on your laptop.

[jungjinki]

Please find the attached for IOReg of completely working notebook. I saved it while I am having screen through HDMI. It is Dell 7559 SkyLake CPU with two graphics 1) Intel HD 530 2) nVidia GTX 960m running ElCapitan-10.11.6. Its video to HDMI, recognition of graphics memory 1536MB and speed all are OK.
