[Bug] AppleHDAController not attaching to AMD FCH Azalia (0x1022:0x1487) on macOS Tahoe — ASUS TUF Gaming X570 Plus

[MarekSurek]

System:

• Motherboard: ASUS TUF Gaming X570 Plus
• CPU: AMD Ryzen 5 3600
• Audio Codec: Realtek ALCS1200A
• macOS: Tahoe 26.3.2
• OpenCore: 1.0.7
• VoodooHDA: 304
• Lilu: 1.7.2

Problem:
AppleHDAController does not attach to the AMD FCH Azalia controller
(0x1022:0x1487) on macOS Tahoe. No audio output via 3.5mm jack.
HDMI/DisplayPort audio works fine via AppleGFXHDA.

ACPI Path:
IOACPIPlane:/_SB/PCI0@0/GP13@80001/AZAL@4
PCI path: PciRoot(0x0)/Pci(0x8,0x1)/Pci(0x0,0x4)

Device info:
"compatible" = "pci1043,8797","pci1022,1487","pciclass,040300","AZAL","HDEF"

Verified:

• HD Audio enabled in BIOS
• SIP disabled and confirmed via csrutil status
• VoodooHDA installed via PKG installer (not injected via bootloader)
• Device visible in ioreg and IOPCIFamily logs
• AppleALC also fails — AppleHDAController never attaches to this device

Kernel log:
IOPCIFamily found device at [i32]13:0:4 (0x1022:0x1487) but
AppleHDAController never probes it. Zero AppleALC log entries for this device.

Tested layout-ids: 7, 11, 15, 21, 32

Conclusion:
AppleHDA/AppleALC completely ignores AMD FCH Azalia on Tahoe.

Provide please dump with getdump utility.
AppleHDAController is not needed for VoodooHDA.
Open VoodooHDA.kext/Contents/Info.plist and change here
IOPCIClassMatch=...
to
IONameMatch=AZAL

and
InhibitCache = true

✅ Working solution for ASUS TUF Gaming X570 Plus + ALCS1200A on macOS Tahoe 26

After a long debugging session, VoodooHDA 312 is working with some tweaks.
Leaving this here for other users with AMD X570/B550 boards.

Setup:

• Motherboard: ASUS TUF Gaming X570 Plus
• Audio Codec: Realtek ALCS1200A (0x1022:0x1487)
• ACPI path: _SB.PCI0.GP13.AZAL
• macOS: Tahoe 26
• Installation: kext injected via OpenCore (EFI/OC/Kexts)
• Headphones connected to rear panel (green jack)

---

Required Info.plist changes:

Open the plist for editing:

1. Copy to Desktop first (the file is owned by root):
   cp /path/to/VoodooHDA.kext/Contents/Info.plist ~/Desktop/Info.plist
   open -a TextEdit ~/Desktop/Info.plist

2. Make these changes:

   IONameMatch: change HDAS → AZAL
   (AMD X570 uses AZAL as ACPI device name, not HDAS)

   InhibitCache: false → true

   VoodooHDAEnableVolumeChangeFix: false → true
   (without this, audio cuts out when moving the volume slider)

   VoodooHDAEnableHalfVolumeFix: false → true
   (little improve for non-linear volume curve)

   LayoutId: set to 2 for 7.1 channel layout

3. Copy back and rebuild cache:
   sudo cp ~/Desktop/Info.plist /path/to/VoodooHDA.kext/Contents/Info.plist
   sudo kmutil install --volume-root / --update-all

4. Reboot

---

Important — macOS Tahoe privacy approval required:

After first boot, go to:
System Settings → Privacy & Security → scroll down → approve VoodooHDA
Then reboot once more.

---

Notes:

• AppleALC does NOT work on Tahoe with AMD FCH Azalia —
  AppleHDAController never attaches to 0x1022:0x1487
• "VoodooHDA must NOT be injected from bootloader warning" is outdated —
  injection via OpenCore Kexts folder works fine on Tahoe
• Small audio crackles during volume change are still present
  but audio no longer cuts out completely

Thank you for the great kext and quick support!

Update — reopening due to new findings

I need to correct my previous summary. After more testing:

Corrected LayoutId results:

LayoutId	Output	Microphone	Slider crash
2	✅	❌	✅ crashes
7	✅	✅ decent	✅ crashes
11	✅	✅ good	✅ crashes
12	❌	✅	-

My previous report saying "audio no longer cuts out completely"
on LayoutId 2 was incorrect — crash does occur on slider release
on ALL tested LayoutIds.

VoodooHDAEnableVolumeChangeFix: true is set but does not prevent crash.

Best overall result is LayoutId 11 (good mic + output)
but slider crash remains the main unresolved issue.

Sorry for the incorrect information in the previous report.
