GUIDE: HDMI Audio

- Sort by reaction score
To clarify, 2 methods; one or the other, remove 1st before installing 2nd
Both IORegs look the same, neither method worked
Binary patch: specify hex editor? in place? not in place, kext installer? kext cache rebuild?
AppleALC: native AppleHDA.kext? location? kext installer? kext cache rebuild?
Attach kext cache rebuild output, if available
[doublepost=1523994350][/doublepost]
IOReg/HDAU/device-id?
I know, I tried that preview AppleALC.kext with the original AppleHDAController.kext first.
May I know with the self patched AppleHDAController.kext. Should I use the normal AppleALC 1.2.6? Or the one that manually edited? My last attempt was with the self edited + builded version.
https://forums.macrumors.com/threads/guide-hdmi-audio.1499797/page-27#post-25971642
Either doesn't work. Then I tried both. Anyway, will try patched AppleHDAcontroller.kext + native AppleALC.1.2.6 now.
For info:
Binary patch,
Hex Editor is HexMiner (I used it for few years already, never give me any issue)
I copied the original AppleHDAController binary to desktop. Edited it. Then put it back to the original place, then manually fix the permission.
Then open Kext Utility, let it install the self edited+builded AppleALC 1.2.6 (not your preview version), and let it rebuild cache.
AppleALC,
YES, with native AppleHDA.kext.
Installed to S/L/E by Kext Utility. And I did let it rebuild cache.
May I know how to get the kext cache rebuild output?
[doublepost=1523996769][/doublepost]This is the IOReg for patched AppleHDAController with the AppleALC 1.2.6 release directly downloaded from here.
https://github.com/vit9696/AppleALC/releases
With this combination. The 1080Ti's audio controller shows driver installed
But still not available in Sound preferences yet.

Kext patch procedure is correct.
Native AppleALC.kext v1.2.6 does not include the AppleHDAController patch for your graphics card, useless.
Do not combine the binary patch with AppleALC.kext, KP possible.
For the 1080Ti's audio controller, you selected the video device, not the audio controller: pcie10de,10ef
The attached IOReg ("patched AppleHDAController with the AppleALC 1.2.6 release") shows AppleHDAController loading, working. Reason, patched binary.
Remove AppleALC.kext. Rebuild kextcache: Terminal:
Code:
sudo touch /System/Library/Extensions && sudo kextcache -u /The reason for no HDMI audio, with the working AppleHDAController, is the Nvidia Web driver.
Restart, Reply with new IOReg and Terminal Output.
Thanks for providing the procedures. Will do that once I back to home.
Question:
Should I remove the Lilu.kext and the NvidiaGraphicsFixup.kext as well?
P.S. I realised that I was selecting the video device on the PCIe page, because what I wanted to show is just the "driver installed" is yes. Anyway, here is the audio device details.

I just removed all AppleALC, Lilu, and NvidiaGraphicsFix kext.
kextcache rebuilded
The binary still patched
HDMI Audio installed
PCI info same as above (shows Audio Controller driver installed), but not working yet
And the attachment is the IOReg.

Audio now works on my GTX 750 Ti with AppleALC and NvidiaGraphicsFixup. For posterity, I've described the procedure below.
1) Install NvidiaGraphicsFixup.kext and Lilu.kext.
2) Obtain the path to HDAU in IORegistryExplorer:
In my case, the path was AppleACPIPCI/IOU0/IOPP/HDAU.
3) Add the path to CodecLookup.plist in the source of AppleALC (unless the information is already included):
4) Form the codec ID by appending de10 (the Nvidia vendor ID) to the device ID that appears under HDAU in IORegistryExplorer:
In my case, the complete ID is de10bc0f.
5) Form the decimal name of the codec. In my case, the name is 4028 (decimal for 0x0fbc).
6) For completeness, find the chip number of the GPU. In my case, the number is GM107 (according to the Wikipedia article on the Maxwell architecture).
7) Include the complete ID, decimal name, and chip number to Controllers.plist in the source of AppleALC (unless the information is already included):
(The only case-specific entries are "Device," "Name," and "Replace.")
8) Rebuild AppleALC (making sure to include the debug version of Lilu.kext in the top-level folder of the source).
9) Install AppleALC.kext.
See also the AppleALC guide.

Expected
10.13.4 AppleHDAController is working
IOReg shows the issue with Nvidia Web driver and Pascal:
If using DP, try other DP ports.
If HDMI, acquire DP2HDMI adapter (for 4K display, an adapter required)

Thanks for the suggestion. I just back home and try different DP. YOU ARE SPOT ON!
There are 3 DP on my reference 1080Ti. The left most port's audio works with simple binary patch.

Thank’s a lot! Finally I got it working on GTX 980.
Sound is ok when I use DP to HDMI adapter. No sound straight from HDMI out but anyway...
One more suggestion, IOReg shows AppleGraphicsPowerManagement.kext is not loading. Make an injector kext to support Pascal graphics with the MacPro5,1 sysdef, search: macOS Native Discrete GPU Power Management.
[doublepost=1524414663][/doublepost]
Nvidia web driver supports sound on all connectors for Fermi/Kepler/Maxwell graphic's cards (except 450,550,560). For Pascal graphics cards, only one DP supports sound and not always.
Your requirement for for a 980 DP2HDMI adapter is not a Nvidia Web driver problem, likely, a HDMIAudio.kext problem.
Thanks for the suggestion, that's beyond my knowledge at this moment. I can learn how to do that, no problem.
However, may I know what can I expect if I successfully load the AppleGraphicsPowerManagement.kext? My GPU's power management seems OK with the Nvidia web driver.

Working with HDMI directly.
VBIOS manages thermal limit by increasing fan speed or reducing frequency. The Nvidia web deriver has no PM. Fermi and previous use thresholds; Kepler, Maxwell and Pascal use P states. Setting AGPM.kext/Sysdef/Heuristic-ID: 4 sets macOS/Nvidia p state PM.
I see.
So, even system info shows AGPM.kext is loaded, but it isn't working properly at this moment. Is that correct?

Does it still work with the security update?
I did SMC reset and CMD+OPTION+P+R due to some other issues, and the sound was lost for some reason on 10.13.4... It shows no input/output devices at all. Putting back default HDA - gives me standart sound (HDMI/DP does not work) but installing new 10.13.3. kext again (which was working previously) removes any sound input/output devices....
Removing/enabling HDMIaudio does not change anything.
[doublepost=1524636466][/doublepost]P.S. On 10.12.6 HDMIaudio works but booting into another installation and then back to 10.12.6 disables HDMI sound for some reason. Reinstalling solves this until reboot to other partition again.

PRAM reset will enable SIP, which disable all unsigned 3rd party kext.
Try disable SIP, it may work again.
Oh great! Will definitely try to. I thouht I might need to reinstall the system.
Does 10.13.3. HDA in 10.13.4. counts as unsigned as well?
[doublepost=1524640570][/doublepost]P.S. Do you have any possible hint why HDMI sound gets disabled on 10.12.6 every time I reboot to another partition and back?

this is the only working solution I had tried the HDMIaudio kext several time the key was indeed to replace the apple kext to the older version.

Thanks for teaching me all about this. I am more than happy to learn new things.
However, still haven't figure out how to make that injector kext yet
[doublepost=1524700837][/doublepost]Or if I can use the same method to patch the AGPMcontroller?
Thank you again! That was the issue. 10.13.3 HDA is functional in 10.13.4. again for me. Standard sound outputs are working. I have latest security update installed, so I cannot check HDMI as there are no updated Web drivers so far. But under PCI I see my 980 listed as Audio device again.
