No Audio Devices - Realtek ALC AppleHDA [Guide]

[herbert456]

Can't get my onboard audio to work on Yosemite => it is not listed as an device in audio outputs
On Mavericks my onboard audio worked via VoodooHDA. As this approach did not work in Yosemite I tried to give the patched hda a try, however without success.
Btw. I have a USB-soundcard attached in parallel which works fine (at least in mavericks it did not interfere with the onboard audio).

So here's my data:
- onboard audio works fine in windows and ubuntu
- ubuntu reports onboard audio as 0x10ec0887 with revision 0x100302 (see attached dump of /proc/asound/card0/codec#0) and it works fine
View attachment card0codec0dump.txt
- I installed realtek alc applehda via multibeast 7.1.1 (ALC887/888b Current v100302, this autom. added the HDAEnabler and HDEFLayoutID section to my org.chameleon.boot.plist)
- DPCIManager shows my onboard unit as an Intel HDA one (0x80861c20) but does not display a codec ID or codec name
- IORegistryExplorer has no entry for HDEF but one for @1B which shows the intel hda card (0x80861c20).
- I have no custom dsdt and am running OSX 10.10.1 installed via UniBeast and booted via Chimera/Chameleon

Any pointers appreciated

See Problem Reporting, Post #1, attach all requested files.

Here you go: IOReg file, applehda, dpcimanager screenshot:

View attachment AppleHDA.kext.zip


Regarding "System Information/Hardware/Audio/Intel High Definition Audio", there is no such entry only my USB device is listed there.

And for the rest (chameleon bootlist config and bootlog as shown in dpcimanager):

Anything missing?

there is no such entry only my USB device is listed there.

Problem: no dsdt/HDEF
Fix: see Post #1,
2. HDEF Verification/IORegistryExplorer see Tools 3.

1. IOReg/Search: HDEF
2. If no IOReg/HDEF
   1. IOReg/Search: @1B
   2. Add dsdt/HDEF, select one method and implement

4 methods noted.

Thanks alot toleda!! It works now fine!
At first I was a bit confused by the structure of the tutorial (post #1) but now I understand that my usecase was already covered
(I went with the HDAEnabler kext, as I still don't fully grasp what the dsdt and ssdt approaches would induce)

Thanks again for your help

I think in essence the easiest way (for me) would have been to just tick "MultiBeast/Drivers/Audio/Realtek ACLxxx/Optional HDAEnabler/Audio ID:1" (anyway, now I installed the HDAEnabler1.kext from your git repo via DPCIManager). Thanks again

Problem: No Output Devices Found in SysPref/Sound + No CodecID in DPCI Mgr

Codecs appear to be disabled in the BIOS.

Thanks,

looks like audio is not an option on this board then

• No output devices
• 10.10.1/GA-H97M-D3H/F4 6-28-2014, verified HD audio on, UEFI boot/i3-4360 using HDMI
• clover injection
• IOJones attached
• default AppleHDA.kext attached
• no AppleHDA patches installed (see below)
• console log attached
• DCPI screenshot attached
• audio_realtekALC-100.command (see below)
• chimera/chameleon (N/A)
• Clover config.plist attached

Attempting to run the AppleHDA patcher (audio_realtekALC.command) that you committed yesterday resulted in the original AppleHDA.kext being deleted from S/L/E, a folder being created on the desktop but nothing in it, and no other changes. Bug in the most recent commit maybe? See the last attached screenshot.


I extracted a new AppleHDA.kext from Essentials/BaseSystemResource/BaseSystemBinaries with Pacifist and rebooted, it loaded ok it seems but I'm back at square one, showing successful clover injection on ID1 but "no output devices".
