Hey guys, after countless hours of work i finally got Leopard installed on my computer (Gigabyte P35 DS3R, E6600). The Natit and LAN drivers worked perfectly without having to modify anything. I am, however, having a great deal of trouble trying to get my audio (ALC889A) to work. I've read all the forums which all say the same thing; download alc889a.zip (ALCinject.kext and AppleHDA.kext) and then copy them into extensions and go to terminal and type:
sudo -s
sudo chmod -R 775 /System/Library/Extensions/ALCinject.kext
sudo chmod -R 775 /System/Library/Extensions/AppleHDA.kext
sudo chown -R root:wheel /System/Library/Extensions/ALCinject.kext
sudo chown -R root:wheel /System/Library/Extensions/AppleHDA.kext

After that i delete Extensions.mkext and reboot. When i reboot i get the error that says kexts were not installed properly. This is strange because when i had tiger installed on this exact same system i followed the same steps and audio worked beautifully. Has something changed since Tiger? Is the kext installation method different in Leopard? Any help is greatly appreciated. Thanks.

EDIT: fixed! turns out all i had to do was create a password.

It is the same method installing .kexts. Next time try doing following:
chmod ...
chown ...
kextload -t (this -t is to see if kext loads sucsesfuly)

On reboot boot Leo width -F

I think that should help. (it is working on my Leo)

can you write step by step? how, help

Let me tell you what worked for me! I installed the 889a kexts and got no audio, but with them installed, I installed Cmedia 8738 drivers and ALL ins and outs now work on my 889a card on my g33 gigabyte board! I wound up trying those drivers cause i bought a cheap card based on the cmedia and noticed digital out and the card i bought didnt have any I removed the card and selected built in speakers as output and its been working ever since! I'll upload the kexts i have when i get home

It really works though cause i have reinstalled them at least 6 times trying to resize the darn 15gb partition and its worked every time lol

so with the Cmedia 8738 driver i should be able to get 5.1 surround sound? if you could send me a link i would really appreciate it, thanks.

That zip contains the files and instructions I used to get it to work. I had to do the CMI8738PCIAudioDriver instructions as root and it worked. I dragged the .sh file to a terminal window and ran it then followed the instructions in the text file. Reboot and you should have sound!

Well, has it helped, anyone?

I'm using a gigabyte G33 board btw. The file' been downloaded multiple time, has no one got any feedback?!

did you get spdif to work?

Yes! Thx a lot! Got the alc889a on a P35-DS3R working with your driver.
It also shows me a digital output now
Done on 10.5.1 efi6 and ToH sleep kernel

Thx again

I can confirm it has worked on a Gigabyte P35-DS3... i dunno why it worked but it did.
Just install CMI8738PCIAudioDriver kext in the usual way with the ALCinject.kext and AppleHDA.kext and the sound started working.

Thanks a lot.

do i have to chow and stuff or can i delete old kexts put new ones, delete extensions, repair and be fine?

Worked great on my parent's GA-P35-DS4 r2.0..

thanks ptype

I have the GA-P35C-DS3 with the ALC889A sound chip.

No luck, this it what I did:Using Kext Helper I installed: AppleHDA.kext and ALVinject.kext.
Then using AppleHDAPatcherv1.20 I installed: alv888.txt (okay, I now know that was the wrong file...).
Then as it says above I installed CMI8738PCIAudioDriver.kext (again with Kext Helper).

Any advice on what I can do?So far no sound and no sound Input or Output devices listed in System Preferences.
I'm using Leopard 10.5.1 (Kalyway).

*few minutes later*

Success!

I just added these kext and it's working:

HOW INSTALL KEXT FILES propetlyi dont understand this OS
help me

A great utility for installing kext files is kext helper. Here is a link:

http://forum.insanelymac.com/index.php?showtopic=54098

Had the same prob with getting errors whith installing kext files into the extensions folder with leo and this prog saved me hours of stress. You must have a login password in order for it to work however (easily set in the system preferences). I think it is designed only for installing kexts into your extensions folder but I could be wrong on this.

Thanks a lot.

This worked perfectly!
Thanks.

Thank you very much Prototype!!! You got my ALC 889A to work on my Psytar running Leopard. I had tried all the installs, terminal etc. Thank you again for taking the time to post, yours may be the easiest method yet. McLovin

hey prototype_sx!
it fixed sound on my GIGABYTE GA-EP35-DS3, thanks a lot!

hi!

i've tried all the above suggestion, but my sound still doesn't work properly. the weird thing is that my rear satellites have sound, (in a 6.1 system), but the others have not.

i'm running ideneb v1.3 10.5.5

any ideas?

thx

I got this working one time on my P45 DS3R, but the next time I rebooted it wouldn't work again. I tried reinstalling the kext and nothing. I did download the updates, which included itunes and java, not the 2.5.6 update. Is it possible that was the problem.

Any help would be greatly appreciated.

P.S.

Thanks for all the other work you guys have done. I never would have got this working at all with out these forums.

Ok, I finally got the ALC889A sound to work with iDeneb v1.3 Leopard OSX86 10.5.5
My board is a Gigabyte EP35-DS3 rev.2.1

Here is what I did:

1) remove any trace of ALCinject and AppleHDA you might have from previous attempts.
to do this, simply delete ALCinject.kext and AppleHDA.kext from System/Library/Extensions
a password will prompt.

2) download the attached zip file.
it contains a new AppleHDA.kext and a HDAEnabler.kext (ALCinject is NOT needed anymore).

3) install AppleHDA.kext and HDAEnabler.kext
for this I used OSX86Tools from pcwiz


4) After that, in OSX86Tools i chose

Clear Extensions Cache, then
Set Extensions permissions

5) Reboot and tada! the System Profiler shows an Intel HDA present under Audio.
it also seems to recognize the S/P-DIF Out, although I cant test it cause i only have headphones.

The microphone worked immediately.
One thing though, I had to plug the headphones on the front of the case.
Try around several connectors until you get the right one.

Haha, after many many hours wasted all I had to do was plug the audio into the front headphone jack. I forgot they even existed!

Many thanks for solving the only issue with my hackint0sh!

THIS WORKS 100% FIRST TRY! Just follow the instructions step by step and you will have digital sound in no time!
