NEW VoodooHDA Intel High Definition Audio Driver
 

This was first posted at Uphuck forum by Pere. i tried this last night and my Intel High Definition Audio worked immediately after installing the kext and removing the AppleAzaliaAudio.kext, I did not even need to reboot my HAC after installing the kext.

Here is download link of compiled kext:

Install to System/Library/Extensions and erase ALCinject or HDAenabler if you have it. Nothing else.
Move out from your extensions folder the driver Appleazaliaaudio.kext so you know the patched Azalia audio driver is not interfering.

Main project place:

I can't reach the link. Post it here as attachment, please.

Here you go, attached to this post now :)

Unfortunetely there are still some distortion issues with some HDEF audio controllers...
For example my ATI SB450 audio card (0x437b1002) doesn't work so great with it...
I'm sure with some work this will be the best HDEF audio driver available though...

It works great for me.

You're lucky... severe distortion and sometimes even echo on ALC861-VD...
I've checked the source and I haven't found a clue on fixing that...
My solution was thus self-patched AppleHDA...

Works perfectly, even update to 0.2.2 version, with prefpane.

This is the only way to have sound working on my Toshiba X205-SLI6 laptop with ALC 268
0.2.2 w/ prefpane works nice.

I am having the same problem on my ALC268.

For now, I think I will just stick with AppleHDA.kext and HDAEnabler.kext

Thank you!
 

It works ok on my Conexant cx20549 (Venice) without any complications!
Awesome!
