VoodooHDA

VoodooHDA is an open source audio driver for macOS based on the FreeBSD snd_hda driver. A replacement for AppleHDA.kext on Hackintosh machines — analog and HDMI audio.

Compilation.

If you are using systems up to Catalina then open project tranc/VoodooHDA.xcodeproj

For systems BigSur and up you have to download the project VoodooHDA also download MacKernelSDK

git clone https://github.com/joevt/MacKernelSDK.git

(this is tested version) and make a symlink into project

cd /path_to/VoodooHDA/
ln -s /path_to/MacKernelSDK MacKernelSDK

open project tranc/VoodooHDA_BS.xcodeproj and compile

download VoodooHDA.prefPane

1. go to the Release302 of my Release
2. download VoodooHDA.prefPane.zip
3. after downloading, extract it

NEW in VoodooHDA — Bootloader injection without any workaround

Apple's complete IOAudioFamily source code (v740.1) is now compiled directly INTO VoodooHDA.kext (see the IOAudioFamily/ folder — APSL 1.1 license notice included).

The original VoodooHDA depended on the external IOAudioFamily.kext — which is NOT in the boot kernel collection since macOS Big Sur (11). That is why bootloader injection failed since 2020 with:

OC, Clover: Prelinked injection VoodooHDA.kext () - Invalid Parameter

With the family embedded, VoodooHDA's only dependencies are kernel KPIs + IOPCIFamily (which always exist at boot) — exactly like AppleALC.

Result: ONE kext, injected directly from the bootloader, on macOS 11 to 26.

What changed vs the original

• Added: IOAudioFamily/ — Apple's IOAudioFamily 740.1 sources compiled into the target
• Changed: OSBundleLibraries reduced to IOPCIFamily + kernel KPIs (IOAudioFamily and IOGraphicsFamily dependencies removed)
• Changed: VoodooHDA personality IOProbeScore = 99000 (deterministic HDEF claim)
• Fixed: 10+ family source files — compat macros restored (IOMallocType / IOFreeType / require — removed from modern SDK headers)
• Removed: IOGraphicsFamily dependency (framebuffer notifier call neutralized — HDMI pipe auto-activation feature is not in V-3.6.9 )

V-3.6.9x — Installation (OpenCore / Clover)

1. Exclude other Audio kexts (AppleALC, etc.)

2. Copy VoodooHDA.kext to EFI/OC/Kexts/ (or EFI/CLOVER/kexts/Other/)

3. OpenCore: config.plist -> Kernel -> Add -> one entry:

   BundlePath:     VoodooHDA.kext
   PlistPath:      Contents/Info.plist
   ExecutablePath: Contents/MacOS/VoodooHDA
   Enabled:        YES
   

4. No other steps. No SIP changes — works with SIP fully enabled (verified: macOS Tahoe 26.7.1, OpenCore 1.0.7, csr-active-config = 00000000).

5. Reboot.

V-3.6.9x — Known limits

• Audio output still depends on codec support — the same per-machine lottery as every VoodooHDA version (some codecs work, some don't)
• HDMI pipe auto-activation (IOGraphicsFamily feature) is not present in 4.0
• The prefPane settings apply as usual (e.g. VoodooHDAEnableVolumeChangeFix)

Installation (classic — /Library/Extensions, all macOS versions)

1. Exclude other Audio kexts

2. Set SIP disable kext or just

   sudo nvram csr-active-config=0xA85

3. Reboot

sudo cp -R /path_to/VoodooHDA.kext /Library/Extensions/
sudo cp -R /path_to/VoodooHDA.prefPane /Library/PreferencePanes/

5. Wait while the system saids that the kext must be approved
6. Go to System Settings and approve the kext.
7. Reboot.
8. Enjoy your favorite music.

Which method to choose?

Method	macOS	Steps	SIP
V-3.6.9x — Bootloader injection	11 - 26	Copy kext + one OC entry	Full SIP works
Classic — /Library/Extensions	all	Copy + approve	Lowered (0xA85)

Fix for Mic is showing but not getting any input (AMD/Intel)

1. Go to the System Settings>VoodooHDA.
2. Then select your microphone.
3. Set the IMix & Speaker slider to maximum. Mic should work.
