No Audio Devices - Realtek ALC AppleHDA [Guide]

[afinity]

The realtekALC script backs up the original AppleHDA.kext to Desktop/audio_ALC889-10.10.2/AppleHDA-orig.kext. Rename to AppleHDA.kext and install with KextBeast, Kext Utility, etc.

Thank you learned something new. I used kextbeast put AppleHDA.kext back and ran audio_cloverALC-100_v1.0.4

now i have the devices back up, but the line out seem to be pointing to the wrong ports, have to plugin to black and orange port and headphone jack in front is internal audio but when i plug it in it changes to headphones. I really cant complain cause its working but just wanted to point it out! thank you for your help!

ioreg.ioreg is for a different system, not helpful
OS X/X99 audio is not natively supported, see Post #229, Haswell-E + X99 Motherboard Temporary Guide - OS X 10.10

Thanks for the reply, I tried to take out the npci=0x3000 but I couldn't boot into yosemite, is it possible to work with this bootflag in place?
Also, how do I go about installing the SSDT-1.aml file - from the link you sent me?

Works as designed (credit: Apple)

I still use the npci because it's the only way the computer starts

Try npci=0x2000.

• Open Extra
• Rename Downloads/SSDT-1.aml to SSDT.aml
• Copy Downloads/SSDT.aml to Extra

Try npci=0x2000.

Thanks a lot!! It's working Will I have to reinstall the codec at some point? Or now that it's working, I should be ok?

Again thanks a lot!

Thanks again for the reply, I have installed SSDT.aml, but it still doesn't work -

One issue I am having with both methods for Audio_ID Injection:
I go on youtube or pandora and the video and song won't play, also no audio.
even when trying to use a video clip or game that is not online, it will play but no audio.
Without using the Audio_ID Injection my bluetooth speakers works, but with the injection it doesn't either, no audio completely regardless of connectivity.

I tired with npci=0x2000 and ncpi=0x3000 both yield the same result.

Also, I used: realtekALC/patch in place method

Attached I have the results from implementing this.

Would it be the Audio_ID Injection or the Kernel Flag (npci)?

Could it be one of my other Kernel Flags?

Sorry about that, here is the saved copy of it attached.
Let me know if there is any other info that I could provide that may help resolve this.
