After months of waiting idt sound devices finally work in osx! Use this guide to get your specific codec to work .

First lets thank AREOS for his work on getting applehda working for idt in general!

Alright lets start first delete your existing applehda.kext from your extensions folder and use the one provided below:

download and install HDAenabler so AppleHDA will load

now to edit the kext...


Step 1: Codec device id

if your codec is different from the one provided by AREOS you must adjust the applehda binary, the controller plist and the platform plist. to do this you need your specific device id. so once you get your device id compare it with AREOS.

ex. AREOS device id = 0x111D76B0 my device id = 0x111D76B2

now u must convert this hex id to decimal form.

use osx calculator to do so. here is what i got:

ex. AREOS dev id (decimal) = 287143600 my dev id (decimal) = 287143602

Step 2: Edit Binary

ok to edit the apple hda binary u need to first download hexedit (a program for osx to edit binary files).

once you have downloaded hexedit open up your applehda.kext/contents/macos/applehda with it.

in the hex file there are two device ids you have to adjust

search the hex for “B0761D11”. you should find two instances of these hex numbers.

as you can notice the bytes are flipped ie. B0761D11 = 111D76B0

in the two instances you find in the binary, type in the appropriate device id for your card.

Step 3: Edit Platform Plist


Open AppleHDA.kext/contents/info.plist...

edit codecID so it is the device id (decimal form).

ex. CodecID = 2871433602

Step 4: Edit Controller Plist

Open AppleHDA.kext/contents/plugins/AppleHDAController.kext/contents/info.plist

Edit IOPCIPrimaryMatch with your HD audio controller.
Mine is Intel Audio Controller 0x293e8086

ex. IOPCIPrimaryMatch = 0x293e8086

Under HDAConfigDefault edit the codec id again (decimal form)

ex. CodecID = 2871433602

MAKE SURE TO USE HDAENABLER.KEXT NOT ALCINJECT SO APPLEHDA LOADS!



Heres were it can get difficult...

if your loaded applehda doesnt work after this you might have to fill in the ConfigData in your controller plist.
