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)

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 :D

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

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!

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.

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:

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

http://forum.insanel...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.

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
