No Audio Devices - Realtek ALC AppleHDA [Guide]

[MIcahTautkus]

Read Post #1 of the linked thread. The patch does the edit. Unless you are an ACPI expert, use the tool. AppleHDA.kext is not an enabler, a patched version is required for OS X audio. Post the dsdt after the HDEF edit.

Ok! So I was of course overthinking this, and I finally understood the guide properly. So I did precisely what the guide said and got it all working! Thanks much toleda for all your work into this thread.

Now I have to solve my problem of "Waiting for graphics accelerator to start" haha.

Let me know if you want me to post the final working dsdt.aml

3 injections installed, only one is required.
Use dsdt injection, remove:
1. S/L/E/HDAEnabler1.kext
2. E/org.chameleon.Boot.plist/HDAEnabler & HDEFLayoutID
Reply with new IOReg.

Update:

RESOLVED! Thank you! After following your instructions I reviewed the IOReg and saw a strange device ID. Ran Multibeast with 889 driver and now all is good. On to resolving TRIM and eventually iMessage. Thanks again.
