Realtek ALC892 VoodooHDA v2.7.2 version modded for ASUS motherboard and not only (especially tested on ASUS P8Z68-VPro BIOS version 1101).

4 CHANNELS VERSION by tHEVisitOR.

device id <20 1c 00 00>
vendor id <86 80 00 00>

(No HDMI function)
After the 2 channels version, I try to enable the others lineouts. This time 4 channels are successfully active: Line Out GREEN and ORANGE.
These files have:
Line-Out(Green Rear) (2 channels)
-work great, NO noise like turn on/off caused by AppleHDA multibeast 4.2.1 combo, NO continuous noise like wind by VoodooHDA 2.7.x. If you hear any noise go to System Preferences - VoodooHDA panel - and turn on SSE2
Headphones(Green Front) work well.
SPDIF out work (Orange).
Microphone (Pink Front/Rear) work well.
Line-Out (Orange Rear) work great.
There are also 2 channels from LineOut Grey Rear not tested, if you can test it and they successfully work please comment below, thanks.

Installation instruction:
-clear system cache
-if you have DSDT with HDEF patch, delete HDEF section.
-delete ALL audio kexts like: AppleHDA, HDAEnabler,ALC8xx, AppleHDA1062 (remember to eliminate especially this last one )
-install VoodooHDA.kext with Kext Wizard or any other kexts installation program.
-to install VoodooHDA panel on System Preferences do:
on terminal switch to root user and:

Code:

cp /User/<your name>/Downloads/VoodooHDA.prefPane.tar /System/Library/PreferencePanes
cd /System/Library/PreferencesPanes
tar xvf  VoodooHDA.prefPane.tar
chown -R root:wheel VoodooHDA.prefPane

That's all, now reboot and test it.
PS Please read and follow instructions, if you dont, you can have Kernel Panic.

With 4 channels you can try to build combined device to enable 3.1 system.
Next versions in future we working to enable 5.1 Surround and 7.1 and HDMI function, stay tuned and enjoy sound.
That's all , enjoy it.

WHAT IS VOODOOHDA SSE2 Enabler??? It's only an AUTOMATIC SSE2 ENABLER FLAG script , if you dont want dont install it.
P.S. I've added a script called also VoodooHDA SSE2 Enabler, you can easily install it on Application, then go to System Preferences-Universal Access and flag to Enable access to assistent devices then go to System Preferences - Accounts and groups - your account and go to Login Elements to add at login this script. Every time you login this script enable in auto SSE2 and Enhance stereo.
