Okkk I have been trying to get Audio working on my install but I have no luck. I have been looking and looking and someone said about replacing some files with ones from the Darwin CD. I did this, when I reboot the "IOAudiofamily.kext" claims that it has wrong permissions? And if I try to kextload it it says that it isn't authentic. So main point is, how do I sort my IOAudiofamily.kext out and once that is sorted what do I do to get sound working on here?
Thanks a lot

have you tried setting the permissions in terminal?
in case:
as root (or with sudo) do:

chmod -R 755 /System/Library/Extensions/IOAudiofamily.kext
chown -R root:wheel /System/Library/Extensions/IOAudiofamily.kext

(from memory, please excuse any errors)

thanks, that solved the problem with the IOAudiofamily.kext file. But I still have no sound, I have tried the tutorial on the wiki but no luck. Has anyone had any luck with getting Realtek AC97 Audio working?

make sure your AppleAC97Audio.kext is present then:
cd /System/Library/Extensions
sudo chown -R /System/Library/Extensions/AppleAC97Audio.kext
sudo chmod -R 755 /System/Library/Extensions/AppleAC97Audio.kext
kextload AppleAC97Audio.kext
chown -R root:wheel /System/Library/Extensions
cd /System/Library/Extensions/AppleAC97Audio.kext/Contents/PlugIns/
kextload AppleAC97AudioIntelICH.kext

then clean your extensions cache:
rm /System/Library/Extensions.kextcache
kextcache -k /System/Library/Extensions

There are a few commads that I think I used, they shouldnt be harmful....I havent never used a Mac
untill I got started on osx, I dunno much except my sound wasnt workin and after lookin through a lotta
topics then with help from DrJägermeister
I think he is the audio guru around here
also the wiki guide is good

Sadly I still have no sound. and I tried the wiki guide but no luck
Any other ideas?
Many thanks

hi, i've the same trouble...
when i type this line "sudo chown -R /System/Library/Extensions/AppleAC97Audio.kext"
it says :"chown: illegal option --"

What Realtek audio device is it you're using? cos some use the AppleAzaliaAudio.kext driver and have you got the IOHDAudio.kext? cos it may need that also

You should have written:

sudo chown -R root:wheel /System/Library/Extensions/AppleAC97Audio.kext

I also am having trouble with Realtek. My Device ID is:

0x24c58086

8086 is Intel's vendor ID. What should I do? I did this install using the Generic.Install.DVD, and now I've heard that it doesn't have a lot of neccesary kexts.

Could someone post AppleAC97Audio.kext for me? The Generic DVD Install doesn't have it, and I'm burning without audio here. (And no, I'm not dling the whole damn darwin cd for this, nor am I installing deadmoo over the current install)

EDIT: Finally got it working, found the kext in another thread on this very forum (thanks to google, no thanks to the forum search feature. Honestly!)

YAY! Almost fully working osx86 ultralight! Taking pics now!

You'll find the zipped kext you need in this post side 2 at the end. You don't need to configure it, your ID 24C58086 is configured for ICH4. You evtl need to load the kext yourself (like in the posting). This soundcard should work then.

You need to boot with -x that you will have some sound
