    hey @toldea thanks.

    This is what I did so far. I uninstalled VoodooHDA by drag/dropping the .kext file from S/L/E.

    Then from your guide, I downloaded AppleALC.kext and mounted EFI > KEXT > Other (screenshot attached)

    Then I tried to run command downloaded from your guide (audio_codecdetect_v2.3.command). Then it gave me the no permissions error (attached) I have changed permissions to admin, user, others to "Read & Write" but still gives me that error when I double click.

    Please help!!!!

    Open Terminal and run "chmod +x" on the audio_codecdetect_v2.3.command. I think that corrected the permissions when I had the same issue.

    Thanks I tried that. but it says wrong path or something like that. I gave up already. Using VoodooHDA for the time being. Do you think @tonymacx86 and team will release a version of Multibeast for APFS? It would make life so much easier.

    I followed this guide to the letter and I now have audio input/output devices showing up.

    However I am now having an audio/video playback issue. video and audio won't play. Stuck at 0:00

    Any help would be much appreciated.

    Thanks!

    Hi guys, having real issues trying to get my audio to work. Was working flawlessly before updating to High Sierra. Basically, my audio problem seems to be located in the wrong layout-id. In my case its using Audio ID: 7. Here's a screenshot of my DPCI Manager https://cl.ly/3w0o02251C3U + System Report https://cl.ly/1I2Q0L1m2p34 (which shows no codec in audio) but shows in PCI (https://cl.ly/203r2t1z0Q1k).

    Audio: Realtek 1150
    OSX Version: 10.13 - https://cl.ly/3w0o02251C3U
    Motherboard: GA-Z97X-UD5H
    CPU: Intel Core i7 i7-4790K
    GPU: Asus STRIX-GTX980-D C2OC-4GD5 256 Bit Nvidia GTX 980
    IOReg (file): https://cl.ly/213w3L3A0V1Z
    System Preferences Sound: https://cl.ly/3q1d3Z2V3030
    Clover plist: https://cl.ly/442G0y3l0r3m
    DSDT: https://cl.ly/283v1200192F
    Boot log: https://pastebin.com/Ye2jPdLF

    Hope this is all enough information, thanks in advance guys!

    Do not use a file sharing service, put the files in a folder, compress and attach the zip.
    IOReg shows audio is disabled in the BIOS
    Attach the following files:
    Code (Text):
    9:286  0:000  Inserting SSDT-HDEF-2.aml from EFI\CLOVER\ACPI\patched ... Success
    9:286  0:000  Inserting SSDT-HDEF-1.aml from EFI\CLOVER\ACPI\patched ... Success
    9:287  0:000  Inserting SSDT-XOSI.aml from EFI\CLOVER\ACPI\patched ... Success

    Thanks @toleda ! I've uploaded the file. Interesting, so let me see if I can enable the audio in the bios!

    NOTE: Also its strange that no audio codec is detected now, where as before it was :S
