Mavericks: No Audio - Realtek ALC AppleHDA [Guide]

[Davirus]

X79 dsdts do not have device (HDEF). Solutions:
1. Add dsdt/HDEF, see How to Add or Edit dsdt/HDEF v2
2. Install ssdt/HDEF, see toleda/audio_ssdt_enabler

Interesting.

So that means that even my MOBO doesn't really need a patched DSDT i still need it to make thee sound works?

No codecs are recognized in DPCIManager. Device ids indicate HDMI Audio controller of my video card (GV-N640OC-2GI) and an Intel device, however my motherboard (GA-EP45-UD3P) has ALC889a.

I was using this motherboard with old video card (geForce 7600gt) on Snow Leopard and onboard audio was working fine. However when I upgraded to Mavericks, I upgraded to new video card (640gt) and now ALC889a audio controller doesn't show up. I confirmed with Linux live boot that onboard audio (ALC889a) appears to disappear when new video card is installed.

Am I screwed with this video card or should I keep trying? I think I understand that if DPCIManager can't see it, I'm out of luck.

OSX: 10.9.4
Motherboard: GA-EP45-UD3P
BIOS ver: F10
Procedure/Guide Used: non-DSDT

I tried the new applehda kext from github. Still same error. Unable to hear audio after sleep 10.9.4 update. Please help.

No codecs are recognized in DPCIManager.

Graphics card has no effect on onboard audio.
Your motherboard has dsdt/AZAL rather than dsdt/HDEF. Your choices are:
1. Edit dsdt, How to Add or Edit dsdt/HDEF v2
2. Try HDAEnabler1.kext, Post #1

I tried the new applehda kext from github. Still same error.

No surprise, native AppleHDA.kext problem; use search for temporary fixes. Unknown if a solution will ever be found.

Sorry to interrupt. I do not understand computer language. I just built my first hackintosh. I am ver proud of it. Everything is perfect. Sound keeps one coming and going. Now no sound. Even video stops playing after 10 seconds in the browser. I used all recommended parts. GA-H87N version 1.1 no wifi, samsung evo ssd, crucial ballistix sport 8GB, Tp link wifi card. I am connected via top Hdmi port. Just installed 10.9.4 two days ago with multibeast 6.4.0. I selected ALC892 and HD Audio in DSDT free mode during installtion.

I looks like an extremely long thread, You might have already answered this one. But please point me in the right direction again.

I also read that multibeast 6.1 fixes it. Please let me know what to do.

Thanks in advance.
