    892 audio is configured correctly
    Kaby Lake audio fix is not working, try a different method.

    Tried method 1. with no success.
    Deleted FakePCIID.kexts from Extensions and tried method 2.
    Did method 2 with no success. Messed up with the config.plist file and had to do a reinstall.
    Now with a fresh install tried method one and didnt work.

    What is the correct procedure to delete kexts from method 1 and fix the patches of method 2 before jumping onto method 3?

    Move FakePCIID kexts to trash. Occasionally, installing newly downloaded kexts solves the problem
    Install backed up files, otherwise, remove edit added

    I removed the files and installed SSDT-HDEF-HDAS-2.aml. My dual screen set-up promptly stopped working! (Currently running with my Displayport monitor only, turning on the HDMI monitor after booting to the desktop no longer works). Been trying to redress that problem without success, hence the delay in getting back on this issue, and may also explain some changes to the files (attached).

    I managed to make it work with a fresh install with FacePCIID kexts. But I have a bug. Every x amount of time (can be every 10seconds or every minute) I get a sudden loss of audio for half a second. Do you know what it could be? I can make a recording of the problem if it helps.

    EDIT: It doesn't happen if I connect the speakers to the case headphone port. It only happens if it is connected to the green MoBo port.

    SOLVED: Turning the System definition from Mac Pro to iMac solves the problem.

    1- No audio from any jacks – audio devices are seen in system – no sound assertion errors.


    *Using patched AppleHDA [attached]

    *Using a kext injector for ‘configdata’ [attached]


    2- 10.6.8

    SuperMicro X8DAH+F+LR, latest and final BIOS Version [X8DAHLR1.624]

    (2X) XEON 5680 CPU(S)

    NVIDIA GTX 480 [FLASHED FOR MAC]


    3- N/A: USING CUSTOM LAYOUT, PLATFORM XML’S, PATCHED HDA, AND CONFIG DATA INJECTOR KEXT


    4- IOREG- ATTACHED


    5- APPLEHDA- ATTACHED


    6- INJECTOR KEXT- ATTACHED


    7- N/A- NO SOUND ASSERTIONS PRESENT


    8-


    a- N/A- DPCIManager not compatible with 10.6.8

    b- Attached

    c- Attached


    9- N/A


    10- CLOVER CONFIG LIST- ATTACHED


    11- N/A



    I have also attached my DSDT and codecgraph dumps – I believe the problem has to do with EAPD though I have patched the pinconfigs for EAPD on the nodes with EAPD. I have two lineouts each with EAPD node 20 and 21. EAPD



    PS- I have to use Snow Leopard on this machine because it is a Pro Tools box in a studio. Getting audio to work through AVID devices is no problem so it is functioning as a DAW computer but some of the other engineers don’t like using Ableton Live with anything but onboard sound. This machine is ‘stuck’ in 10.6.8 [though this was best OSX version in my opinion] because the cost of making a new Pro Tools machine with all the software and plugins would set us back about $30,000

    This is the work of a different developer, no knowledge of this method.
    Suggestions
    1. Headphones (front panel green) is connected, mutes motherboard green. If nothing is connected to front panel green, case or connector failure. Disconnect front panel and verify motherboard sound.
    2. Install native AppleHDA.kext and remove injector kext. Run Realtek ALC AppleHDA/cloverALC. Reply with new files,

    Do you have a version for 10.6.8?
