HDAUniversal - AppleHDA-like Audio Kext for macOS Tahoe and Hackintosh Systems

[Mirone]

@deeveedee 

Of course, I got your joke. OCLP was designed to let macOS run on older Macs, not Hackintoshes.

That said, I've actually been wanting to add support for HeliPort and itlwm.kext to Wi-Fi Patcher Pro for quite a while.

As for eliminating the need for OCLP... isn't that exactly what @Mald0n and I are doing? 😄

[deeveedee]

@Mirone Yes - my joke was specifically about adding UniversalHDA to OCLP. Sorry I guided us OT.

Yes, for those who want fully enabled SIP.

SIP is system protection against hackintosh.

You can use my clover version and press F8 key on boot screen for dump audio codec like linux

 

@Slice  would be nice to have that feature

AFAIK it presents, may be at F7 key.

... many of us are still running macOS Sequoia on our hacks with SIP fully enabled.

 

Thanks to projects like VoodooHDA.kext and UniversalHDA.kext, we can still run macOS Tahoe on our hacks with SIP still essentially enabled (only setting csr-active-config = <01000000> to allow untrusted kexts in /Library/Extensions).

My HP EliteBook 850 G7 with CODEC ALC 285 is currently using VoodooHDA.kext 4.0 for perfectly working Intel HD audio in macOS Tahoe.

 

Spoiler

 

When I run @MaLd0n's CodecInfo in Tahoe, it doesn't find audio:

I suspect this means that UniversalHDA won't find my audio either.  The corresponding Codec-Info-Report is attached.  

 

What am I missing?  Is it possible to diagnose this before I attempt to install UniversalHDA.kext (since VoodooHDA.kext is working well for me)?

 

EDIT: When I run Codec-Info in macOS Sonoma, it does detect my audio:

The Codec-Info-Report when running Sonoma is also attached.

There were no issues with the import or anything else. So, the problem must be on your end. Use the `alcid=xx` parameter for AppleALC, and HDAUniversal will work. You can also attach a log; read the first post.

[deeveedee]

I'm sure the problem is on my end.  I've tried with boot-arg alcid=11, DeviceProperty layout-id=11, but neither allows Codec-Info to detect my audio in Tahoe.  I was hoping that your audio detection mechanism for Codec-Info was the same as UniversalHDA, so that I didn't have to uninstall VoodooHDA to test UniversalHDA.  I will definitely test UniversalHDA. For now, VoodooHDA 4.0 works perfectly.

But to test HDAUniversal, you have to disable or remove any other audio kexts like VoodooHDA or AppleALC. Both kexts (HDAUniversal and VoodooHDA) don't work well together. No way to maintain VoodooHDA while testing HDAUniversal.

[MaLd0n]

HdaUniversal is an IOAudioFamily-based kext in the sense that it is a real audio driver. It creates and publishes audio devices, engines, streams, volume controls, inputs/outputs, mixer controls, mute, jack sense, and so on. In other words, it directly participates in the `IOAudioFamily` / `IOAudioEngine` stack.

HdaUniversal can use AppleALC layouts as a codec configuration source. These layouts provide codec-specific data such as layout IDs, pin configurations, path maps, node routing, input/output associations, speaker and headphone paths, microphone paths, combo-jack behavior, and other topology information.

Instead of using those layouts to patch AppleHDA like AppleALC does, HdaUniversal can read and apply the same layout information inside its own driver logic. This allows HdaUniversal to configure the HDA codec, build the correct audio paths, create the proper IOAudio ports and controls, and publish the expected input/output devices directly through its own IOAudioFamily implementation. That is why, if your codec works with AppleALC, it will also work with HdaUniversal.

@MaLd0n Without making any other changes, I ACPI-patched my hack's HDAS._DSM and now have working Codec-Info in macOS Tahoe.  I'm sure that UniversalHDA will work now.  Thank you for providing this great solution!

 

Spoiler

 

EDIT: I spoke too soon.  After removing VoodooHDA.kext, rebooting, installing UniversalHDA.kext and allowing it in System Settings and rebooting, I have no audio.  My HDAS._DSM fixes Codec-Info in Tahoe on my hack, but not UniversalHDA.  My logs are attached.

 

1. 1. The zip generated by Collect-HDAUniversal.command: attached 
   2. Your codec model: ALC285 
   3. Your layout-id: 11 
   4. macOS version: Tahoe 26.6 (25G5052e) 
   5. Bootloader used: Open Core 1.0.7 
   6. Whether the kext is installed in /Library/Extensions: yes 
   7. A clear description of the problem: UniversalHDA.kext does not load 
   8. Steps to reproduce the issue: Install UniversalHDA with installer, allow kext in System Settings when prompted, reboot, UniversalHDA.kext is not loaded.
   

Note that audio works without issues using AppleALC in Catalina, Sonoma and Sequoia.  Audio works without issues with VoodooHDA.kext 4.0 in Tahoe.

 

 

EDIT2: This might offer a clue: If I rebuild kextcache with Hackintool, kextstat shows that HDAUniversal is loaded.  Still no audio, but at least the kext is loaded.

kextstat | grep -i hda
Executing: /usr/bin/kmutil showloaded

EDIT3: After rebooting (following rebuild of kextcache with Hackintool, HDAUniversal.kext is no longer loaded).

Thank you.  I was only trying to have working Codec-Info first (which is supposed to be used when AppleALC or VoodooHDA are installed).  I was able to get Codec-Info working after adding a custom _DSM for HDAS.

 

EDIT: The attached archive has the ACPI patches and SSDT that I added to have working Codec-Info.  Without this, Codec-Info did not detect my hack's audio.  I don't believe that all of the properties in the SSDT are necessary, but I didn't experiment further since I was just happy that it worked.  I was hoping that this fix would also work for HDAUniversal, but as MaLd0n explained (and as I observed), this is not the case.

The device is exposed by firmware as HDAS with PCI class 040100, which means generic multimedia audio/SST-cAVS style, not classic HDA 040300.
HDAUniversal currently matches only HDEF or real HDA class 040300, so it never reaches start() and cannot rename the device.
We need controlled HDAS/040100 support with strong HDA validation, not a blind match, to avoid attaching to the wrong audio controller.

[deeveedee]

Thank you for the quick diagnosis!  No worries - I'll switch back to VoodooHDA.kext.

 

Note that I did try renaming HDAS to HDEF after I saw the match in HDAUniversal's Info.plist, but that was not sufficient to load HDAUniversal.

Anyone got Intel HD630 HDMI audio working?

AppleALC works with layout 11 but not with HDAUniversal. Tried all available layouts
