Hi, onboard audio isn't showing up in system preferences. Used to work in Mavericks 10.9. Running OS X 10.10.

Hardware as below:
i7-3820, Gigabyte GA-x79 UD3, Nvidia Geforce GT 610. Shows no codec available according to your guide. Would appreciate some help thanks!

Using OS X Yosemite and MultiBeast 7.0:

When I use the new HDAEnabler.dylib that comes with Chimera 4.0.0, it fails to proper set the layout-id (00 00 00 00) for my GA-Z77X-UP5 TH (ALC 898). However, when I switch back to the HDAEnabler.dylib in Chimera 3.0.1, everything works just fine (audio plays) and the layout-id gets set properly (01 00 00 00.)

No other config options were made other than switching the HDAEnabler.dylib to get the audio working. I suspect something might not be compatible in the new version with this motherboard, but I'm out of ideas on how to debug it further.

Thanks.

1. III No Codec / No Codec ID / Revision. In IORegistryExplorer, layout-id is <01 00 00 00> (see screenshot). In system preferences, no output devices visible.

2. 10.10 running on i7 4770K / Intel DZ87KLT-75K / Nvidia Geforce GT 640

3. Clean install on formatted SSD using Unibeast USB Stick, then installed Multibeast -> only chimera v4.0.0, TRIM, FakeSMC v6.11.1328 including plugins and HWMonitor but no audio or other settings...

4. See attachment

6. Not installed

9. Chimera/Chameleon (if installed)

  1. See attachment

  3. Not installed
  4. Not installed



EDIT:


I have made a small mistake in org.chameleon.Boot.plist:

I have used the following wrong setting:

<key>kext-dev-mode</key>
<string>1</string>

instead now I changed to the correct way which fixed my audio problems:

<key>Kernel Flags</key>
<string>kext-dev-mode=1</string>



thanks for your awesome work toleda!

Not helpful, no attachments.
How about IORegs for each case with the respective HDAEnabler.dylib

Installed Yosemite an the Z87I-Deluxe. Everything working except audio. Used PikeRAlpha's script, repaired permissions/rebuilt caches with kext wizard and rebooted - no audio out devices.
So, copied the AppleHDA1150.kext to EFI/EFI/Clover/Kexts/10.10, deleted kext from S/L/E, repeat repair/rebuild and reboot. Still no audio. IOReg file attached.

AppleHDA1150.kext does not work from the EFI partition, must be installed in S/L/E.
Attach the requested files from Problem Reporting, Post #1.

That is the problem; no codec, no audio. See Post#1, No Codec.



III No Codec


  1. Verify
    1. Boot flag: -x?, disables audio
    2. Boot Installer USB?, disables audio
    3. BIOS/Peripherals/HD Audio/disabled?, disables audio
    4. Reset codec
      1. Shutdown
      2. Pull power cord
      3. Press power button twice
      4. Wait 30 seconds
      5. Plug power cord in
      6. Boot
    5. Defective codec?
    6. Linux/Windows audio?
    7. RMA mother board?
  2. DPCIManager/Status/Codec ID and Revision
    1. If Codec ID is blank, OS X audio is not possible
    2. See II. Problem Reporting
Thanks for your prompt reply! I checked all of the above already, including resetting the codec, so OS X Audio is not possible for my case in 10.10?
