Compiled from 10.4.1 apple sources AppleAC97Audio for Snow Leo with x64 support. (Both x32 and x64 versions of kexts in one). It does not contain AppleAC97AudioAMD, AppleAC97AudioVIA, AppleAC97CodecAD198x plugins, contains only AppleAC97AudioIntelICH, for Intel and nForce 3/4 and maybe later chipsets. Try adding your own device IDs into AppleAC97AudioIntelICH's info.plist.. Also I didn't test audio output through SPDIF and more than 2 channels... need testing. Also made some optimizations and resolved x64 porting issues... listening to the music during an hour... nothing bad have happened yet..

ps. tested on A8N-SLI mobo...

pps added src if somebody needs it.. (7z archive, just delete .zip extension)

Field Note #1 @eMatoS 2010-01-09

Thanks a lot sulphide, with this and your nforceata I'm one step closer to have all my kext ready for 64bits, now waiting for a working kernel...

Field Note #2 @PfhorSlayer 2010-01-29

For what it's worth, I am not able to load this kext on SL 10.6.0. Using kextutil, I get the following error:

(kernel) kxld[com.apple.driver.AppleAC97AudioIntelICH]: The following symbols are unresolved for this kext:
(kernel) kxld[com.apple.driver.AppleAC97AudioIntelICH]: _Debugger

Which seems highly bizarre - why would it not be able to find the Debugger symbol?!

Field Note #3 @PfhorSlayer 2010-01-31

Just today updated to 10.6.2, testing out this driver again. Been playing iTunes for the past.. 30 seconds with no KP!

I'll let you know if I run into any issues

I'm using the exact same mobo as you.

Thanks for the driver!

Field Note #4 @jassman 2010-05-02

Guys, coild you explain how to install this driver on system step by step. Sorry for my nebee

(A8N-SLI, Nvidea nForce Audio, Ati x1600)

Field Note #5 @Gargablegar 2010-06-28

I when i use the Ac97 kexk on my nforce 4 board, (amd) I get wierd results

Mp3s dont play, they play for a few seconds then nothing then a few seconds more
Video audio works fine
System sounds (are totally broken)

Field Note #6 @dragonspeed 2010-06-29 ↳ Re: @eMatoS

A8n-sli

@eMatoSThanks a lot sulphide, with this and your nforceata I'm one step closer to have all my kext ready for 64bits, now waiting for a working kernel...

Hi, I got this MB running very good, I am using Legacy kernel, and everything works very good.
All my kext are now all 64 bits.
I got sleep working even with the apple bluetooth mouse, it starts to work exactly when it wakes.

When you say a working kernel you mean a 64 bit one?

I am now on 10.6.2

Field Note #7 @eMatoS 2010-06-30

Yes dragonspeed, that's the last thing we, the AMD folks, need to run a 64bit snow leopard. Still waiting...

Field Note #8 @dragonspeed 2010-07-03

Today I'll try 10.4 legacy kernel with the 10.6.4 update. Anv says it will be 64. I'll tell you.
osx 86.net/f36/10-4-0-xnu-kernel-for-intel-amd-t6268/

Field Note #9 @eMatoS 2010-07-03

I'm using that one now and it's working fine, you can even boot in 64bit but because of a sysenter (or something like that) problem it won't run any 32bit app.

Field Note #10 @mindlessmissy 2010-07-03

Love it ...

Works perfectly for my a8n-sli se motherboard with on-board sound (no spdif).

Field Note #11 @dragonspeed 2010-07-25

Thanks for the kext, I am using it and it works very well.
I have just a problem that I cannot solve.
I need to have a PS2 keyboard plugged in to get the kext load and running.
Do you have any idea why this could happen?

By the way if you have the same a8n-sli mobo you can give me your experiences with the keyboard stuff.
Thanks for your help.

Also I have a dsdt thead with a nice dsdt for the a8n-sli premium. I think it works in all models.
