is mine an intel audio?

 

 

what if i already edited step 2? i tried overwriting the existing Azalia thingy and when i reboot theres a dialog box saying "The system extension “/System/Library/Extensions/AppleAzaliaAudio.kext“ was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update."

Did you delete the /System/Library/Extensions/AppleHDA.kext?

 

Run Disk Utility in the Utilities folder. Select your OSX partition on the left and click on Repair Permissions on the right.

 

Do you have a Windows partition? I may want you to confirm something there.

So, have you verified you deleted the file and have you run Disk Utility? Have you rebooted to see if the error message is gone?

Try deleting these 2 files for good measure:

 

/System/Library/Extensions.mkext

/System/Library/Extensions.kext

 

And reboot.

 

Go to Terminal (in Utilities folder)

 

Type: ioreg -l > ~/Desktop/ioreg.txt (that is the lowercase L beside the dash)

 

On the Desktop, open ioreg.txt (double-click on it and TextEdit should open it)

 

Find the text: AppleAzaliaController (if it is there)

 

In the block of text right before that, find something like this: "name" = "pci8086,27d8"

 

Give me those values.
