Ive added RAMM'S super kext list to my sources of finding the kext you need for your ac97 audio
. please read through my below post to find it.------------------------------------------------------------------------------------------------------
OK im changing things a bit. before you do anything thing ask yourself "can i move the volume slider?" and if you can then chances are that you DO NOT need the kext so go ahead and skip down the the second part of my tutorial and try it and then if you still cant get things working the try to get the AC97Appleaudio.kext but if you can change the volume it technically means you have sound.
THIS IS FOR 10.4.3!!! (and possibly later versions but not older!)
- Copy or move the kext to your Desktop (EDIT: you must find the kext on your own i cannot give it to you anymore if you need help finiding it pm me or you can look here
RAMM'S SUPER KEXT LIST
once you have aquired the appropriate kext
- Open Terminal
- Type sudo su
- Give your password
Before copy the kext remove the old one:
- Type rm -fr /System/Library/Extensions/AppleAC97Audio.kext
Now copy it again from your user's Desktop:
- Type cp -R /Users/your-username/Desktop/AppleAC97Audio.kext /System/Library/Extensions/
- Type kextload -t /System/Library/Extensions/AppleAC97Audio.kext
if there are no errors Type kextcache -k /System/Library/Extensions and reboot
Of course change your-username to what ever you name it, in my case it's bryan, so the command for me is this:
cp -R /Users/bryan/Desktop/AppleAC97Audio.kext /System/Library/Extensions/
----------------
(thanks to RAMM for the SUPER LIST of kexts)
-----------------
ok now heres what I found out on accident(xD lol) that works for me AFTER FOLLOWING ABOVE INSTRUCTIONS AND REBOOTING (UNLESS YOU CAN MOVE THE VOLUME SLIDER THEN YOU CAN MOST LIKELY SKIP THE TOP SET OF INSTRUCTIONS sorry for the confusion)
go to applications-utilities folder-audio midi setup-audio devices and make sure you select to look at the OUTPUT not the input
. now change the channel setting to 6ch-16bit then go to "configure speakers" and make front left channel 3 then test it by clicking the icon then change the right channel to 6 and test it and TA DA sound.
now if you dont have the choice to make it 6 channel-16bit then for now your outta luck sorry. ask macgirl! lol she can probably help!
if you have any questions just let me kno. if this works for a lot of people maybe we can make this a sticky?
***NEW UPDATE***
if your having permission and or get a message like this:
"kextload: /System/Library/Extensions/AppleAC97Audio.kext: no such bundle file exists
can't add kernel extension /System/Library/Extensions/AppleAC97Audio.kext (file access/permissions) (run kextload on this kext with -t for diagnostic output)"
Then try this:
open terminal
sudo -s
enter password if asked
chmod -R 755 /System/Library/Extensions/<drivername>.kext
chown -R root:wheel /System/Library/Extensios/<drivername>.kext
its not guaranteed to fix your problem but there is a big chance it will atleast get the kext to load properly...now to fix the fact that alot of people cannot see more than 2 or three channels..instead of 6
---------------------------------------------------------
IF YOU HAVE C-Media 8738 and are having problems with it then look around here for a most likely fix
thanks Deffer for tellin me about this! http://forum.osx86pr...h...ic=1656&hl=
