AppleHDA HDMI Audio [Guide]

[toleda]

was going to remove the clover acpi patches of hdas to hdef? or others GFX0 to IGPU?

Both, yes. Those patches disable the ssdts
Missed Post #1/V. Requirements/2. Native AppleHDA.kext/4. Remove/Disable Clover audio/HDMI audio patches
Restart, reply with all files.

I tried to run the cloverHDMI script and get the following in terminal. There is no .aml file in the EFI patched folder. There was one from May 2017. I removed that one and I still don't see the proper terminal readout. (Is there an example of one for Nvidia? I don't see it at the top of this thread.)

Agreement

The audio_cloverHDMI script is for personal use only. Do not distribute

the patch, any or all of the files for any reason without permission.

The audio_cloverHDMI script is provided as is and without any warranty.

Script will not install the ssdt when HDMI audio is already enabled. Remove any previously installed HDMI audio methods, restart, run cloverHDMI

Let me try to remove stuff first. Oh, if I want to use the onboard audio with audio_cloverALC-130.command, which works fine for me, can I still use the HDMI script as well? Or must I choose one or the other now? I would think audio_cloverALC-130.command might not play well together? HDMI worked on my old Nvidia GT640. I've upgraded to a 1050TX. I am getting a DP2DP cable, too. So, before I send files for this problem, I want to rule out some things first.

Or must I choose one or the other now?

One, the other, both; all work.

?? DP2HDMI?

That was my shorthand for this cable: https://www.amazon.com/gp/product/B00YOP0T7G/?tag=tonymacx86com-20

How would you go about installing both scripts? I am sure they both work. But wouldn't audio_cloverALC-130.command change the AppleHDA.kext? Both scripts require a Native AppleHDA.kext?

Also, the only file that was ever in the patched folder was this one: SSDT-HDMI-NVIDIA-PEG0.aml (dated May 5).

That's the only old installation file that I can see. Would I need to remove others and restore the Native AppleHDA? And then what about running Audio_cloverALC-130.command? I would like to know the best order for getting the onboard and HDMI working? I should probably wait a few days for the DP cable to get here. That might make a difference, non?

Neither script edits AppleHDA.kext native files
Double click cloverALC.command
Restart, verify onboard audio

the only file that was ever in the patched folder was this one: SSDT-HDMI-NVIDIA-PEG0.aml

That ssdt supports all Nvidia graphics cards 5 series and newer, no need to run script again.

I should probably wait a few days for the DP cable to get here. That might make a difference, no?

No.
Install 1150 audio/cloverALC any time.
Plug in 1050 when cable arrives.

Okay. My next question is purely for my own information: Why, when you replace the AppleHDA.kext with a native one from (in my case, a real Macbook), do you need to run the cloverALC script again to get onboard audio working? If you reboot with a new copy of the AppleHDA.kext, the onboard disappears from the Sound options until you rerun the script. Curious.

The script adds 2-4 codec specific files to AppleHDA.kext. If those files are not present, no audio.
