Guide created with yahgoo/installVoodooHDA4BSnMont and corpnewt/CsrDecode.

1. In OpenCore Configurator go to NVRAM -> csr-active-config and set

   Key*	Value	Type
   csr-active-config	0x0285	STRING

   

2. Boot into recovery mode, open up terminal, disable SIP with csrutil and authenticated-root, reboot afterwards

   csrutil disable
   csrutil authenticated-root disable
   reboot

   Check SIP status after reboot (should both be disabled)

   csrutil status
   > System Integrity Protection status: disabled (Apple Internal).
   
   csrutil authenticated-root status
   > Authenticated Root status: disabled

3. Check label for Montery volume (might be disk1s5)

   diskutil list

   Mount System-Snapshot of Montery volume by label

   sudo diskutil mountdisk disk1s5
   > Volume(s) mounted successfully

4. Disable GateKeeper and verify status (should be disabled)

   sudo spctl --master-disable
   
   spctl --status
   > assessments disabled

5. Copy VoodooHDA.kext to L/E

   sudo cp -R /VoodooHDA.kext /Library/Extensions

6. Wait for prompt System Extension Updated and accept it. Open System Preferences and allow kext modification, don't reboot.

7. Open Hackintool -> Utilities -> Rebuild KectCache and Repair Permissions, enter password and accept mounting in read/write mode.

8. Seal Volume and create a new snapshot (check if the mount point equals /Volumes/Monterey\ 1/ e.g. with diskutil apfs list)

   sudo bless --folder /Volumes/Monterey\ 1/System/Library/CoreServices --bootefi --create-snapshot

9. Reboot and check if audio device is working as expected.

10. Revert all changes (keep csr-active-config):

    Re-Enable GateKeeper and verify status (should be enabled)

    sudo spctl --master-enable
    
    spctl --status
    > assessments enabled

    Re-Enable SIP after booting in recovery mode

    csrutil authenticated-root enable
    csrutil enable
    reboot

    Check SIP status after reboot (should both be enabled)

    csrutil status
    > System Integrity Protection status: enabled (Apple Internal).
    
    csrutil authenticated-root status
    > Authenticated Root status: enabled

11. Enjoy Audio :)
