How to patch AppleHDA.kext from 10.5.2 and above

[MadTux]

Os X Leopard introduced new codecs, inside their AppleHDA binary so why not to use them.

I will try to explain how to patch and modify a new AppleHDA.kext and hopefully help others in making their one. I believe that here are guys/girls ho want to work on this. I don't know perfect solution, U will need to try and test a bit. Learn and stuff...

 

This tutorial will be based on AppleHDA 10.5.5 kext coz it is latest one

 

Things that we need:

HexEditor: HexEdit_220.dmg

Plist Editor: Property_List_Editor.zip

AppleHDA.kext: AppleHDA.kext.zip

And this generic plist files for PlatformPlugin and Controler plugins.

Platform_Controler.zip

And your own codec dump from Linux, (U can get your codec dump information from Taruga HDAudio.kext, but I never had time to test that)

 

Let's begin:

These are codecs we have in AppleHDA binary

codecs.rtf

And this is a test codec:

Test codec

Name: ALC880

Decimal : 283904128

Hex: 0x10ec0880

Hexedit: 8008EC10

 

First

We need to patch AppleHDA binary with Hexedit

Binary is inside AppleHDA.kext (~/AppleHDA.kext/Contenst/MacOS/AppleHDA)

Open AppleHDA in HexEdit and find a codec dump that is close to yours.

Best way of knowing your card is reading patch_realtek.c from ALSA source:patch_realtek.c.txt

(Or if U are lucky it is the one from original AppleHDA and all that U need to do is create plist files)

 

I will edit AppleHDA binary with 8008EC10. what is backward of 10EC0880

 

So I searched for ALC0262 what is in hex 10EC0262 and changed to 8008EC10

P.S: Try different codecs, for this card 10ec0880, sigmatel codec works too, so U have to make some test, don't stuck on first one. Give it a try.

Second:

After U patched your AppleHDA next it is to create a working PlatformDriver.plist

I made(hopefully) a generic one with all thing that U could have.

How to Platform: Platform.zip

 

Third

- Contorler.plist

Change CodecID to your codec in decimal number and put a LayoutID to 12.

Under PinConfigDefault put nothing.

(It would be best to know your own exact PinConfigDefault numbers, U can obtain them from Vista Registry Explorer, or obtain them thru linux dump(thx Kabyl and The King on this one).

 

Swap Contorler.plist with Info.plist inside Controler plugin

~/AppleHDA.kext/Contenst/PlugIns/AppleHDAController.kext/Contenst/Info.plist

RENAME Controler.plist to Info.plist!

 

 

With this U can hopefully boot and have sound.

 

P.P.S: Change in Controler plist are crucial,but U can boot with your AppleHDA.kext with only this informations in HDAController plist file, but System profiler will not show your inputs.

 

To change from HEX to DECIMAL use Calculator in Applications.

And U have to use HDAEneabler(If U have Intel chipset) or EFI string for your HDA to load, it is better to use HDAEneabler, coz it sets ClassMatch HDA value for Controler.plist.

After all this U have a working latest HDAkext for alc880:

AppleHDA880.zip

 

How to read your codec dump

I will Use a codec dump from user adat6 and try to explane how to find

a pins inside codec dump. And hopefully U will find yours inside your dump

atad6.txt

How to codec dump: Codecdump.zip

 

How to PinConfig, PinConfigDefault or PinConfigOverRides

U can obtain this PinConfig thru Vista registry explorer.

Click on:

START

RUN

and write: regedit (this will start registry explorer)

Search for PinConfig, and U will get something like this:

VistaRegEdit.rtf

Then as user idoc said: "strip out the junk!"

f01c2701 111d2701 111e2701 411f2701 f01c3701 111d3701 111e3701 411f3701 1f1c4701 101d4701 211e4701 021f4701 101c5701 011d5701 131e5701 991f5701 f01c6701111d6701 111e6701411f6701 401c8701981d8701 a11e8701021f8701 411c9701091d9701 a31e9701991f9701 4e1ca701301da701 811ea701021fa701 f01cc701111dc701 111ec701411fc701 2d1cd701951dd701 171ed701401fd701 301ce701111de701 451ee701021fe701

 

then you have to byte flip each double word;

<01271CF0 01271D11 01271E11 01271F41 01371CF0 01371D11 01371E11 01371F41 01471C1F 01471D10 01471E21 01471F02 01571C10 01571D01 01571E13 01571F99 01671D11 01671CF0 01671F41 01671E11 01871D98 01871C40 01871F02 01871EA1 01971D09 01971C41 01971F99 01971EA3 01A71D30 01A71C4E 01A71F02 01A71E81 01C71D11 01C71CF0 01C71F41 01C71E11 01D71D95 01D71C2D 01D71F40 01D71E17 01E71D11 01E71C30 01E71F02 01E71E45>

And after U done this go here so The King can tell U what to do with PinConfig:

PinConfig How to; The King aka XyZ:

 

Next... how to overide your BIOS with HDAVerbs... and get any card to work

 

A made this guide for people who cards are not supported by HDA patcher from Taruga, like mine card ALC880, this guide could be alternative. I don't know what cards are working U will have to try on your one.

If U found this guide useful, I am glad.

 

 

If U ask for help, and want to post a codec dump or registry dump from windows, please post them in text format as atachment. It is easier for every one.

Thanks for the great guide! I'm a bit new to this and have been trying to get the ALC269 codec to work since it's used in many of the new netbooks (MSI Wind, eee, etc). I went through the guide and am able to get system profiler to show the device but osx can't find any audio devices under sound preferences. I tried using the ALC269 codec I posted in this post http://forum.insanelymac.com/index.php?showtopic=126525 but no luck.

MadTux: this has the potential to be brilliant! It seems the old methods aren't working with newer builds of leopard. And BTW: though it's clear English isn't your first language, I, and surely others, really appreciate the effort you've put into posting all this information.

 

Just to clarify: I assume this is the binary at AppleHDA.kext/Contents/MacOS/

We need to patch AppleHDA kext with Hexedit

And I assume you mean that the character pairs are read from the end (ie: backwards):

As U can see when we search in HexEdit with 8008EC10 what is oposite 2 by 2 char of 10EC0880

I'm slowly working my way through this for the 889A codec. There are still some things that are unclear. One thing is how to get the proper EFI string to get HDA to load (is that in com.apple.Boot.plist?). That's worked well for my video card, and I think that's the best for audio from now on.

 

Thanks again MadTux for this thread and I hope you keep revising and clarifying it!

[age_sabres18]

omg this is exactly what im looking for! now i can take matters into my own hands instead of waiting for damn patcher 2.00 lol plz post how to edit the Hard Way and how to read the info in the codec dump

[atad6]

Like I said before, thanks for the great guide. I'm just trying to clarify what you said because I'm a bit new to this and am sure there are others in a similar situation.

 

I'm just trying to figure out what to do with platform.plist. Are the values to be changed below correct?

 

 

I'm also a bit confused about controler.plist. We need to input our codec ID correct? Also is the correct place to put this the codec id that corresponds with LayoutID 12 as shown below? There are multiple listings with codec id which is why I'm confused.

 

After completing these steps do we rename platform.plist to info.plist and replace it with the one already in the folder AppleHDA.kext > Contents > PlugIns > AppleHDAPlatformDriver.kext > Contents > info.plist

 

and the same for controler.plist with AppleHDA.kext > Contents > PlugIns > AppleHDAController.kext > Contents > info.plist

 

I know I'm quite a novice but hopefully this can help others as well!

 

Also I can't wait for the extended guide for how to read pin numbers from a codec dump.

Thank U for your reply about mistaken writen words, and I will try to clarify this tutos, again really sorry for my bad english

 

Like I said before, thanks for the great guide. I'm just trying to clarify what you said because I'm a bit new to this and am sure there are others in a similar situation.

Yes that is correct

 

 

I'm also a bit confused about controler.plist. We need to input our codec ID correct? Also is the correct place to put this the codec id that corresponds with LayoutID 12 as shown below? There are multiple listings with codec id which is why I'm confused.

Yes that is also correct, but in the first place don't put nothing in your Controler plist, remove your codec id from that , this one have IOPCIClassMatch set to AZAL AND HDEF support (0x04020000&0xFFFE0000 0x04030000&0xFFFE0000)

But later after U are shure your AppleHDA.kext is working, U can test various pinconfig inside,

But real deal would be to know how to calculate your real pinconfigdefault

 

 

After completing these steps do we rename platform.plist to info.plist and replace it with the one already in the folder AppleHDA.kext > Contents > PlugIns > AppleHDAPlatformDriver.kext > Contents > info.plist

 

and the same for controler.plist with AppleHDA.kext > Contents > PlugIns > AppleHDAController.kext > Contents > info.plist

This is also right

Thanks for all the help and for clarifying that! How would I go about finding the node/pin id's from this codec dump. I'd use HDAPatcher but the ALC269 codec is unsupported.

Rename your codec in codecdump

Codec: Realtek ALC269

Address: 0

Vendor Id: 0x10ec0269

 

to

Codec: Realtek ALC885

Address: 0

Vendor Id: 0x10ec0885

 

U will got a list of pins, coz patcher is checking only this information of a codec file

Sigh, still no luck. I was able to find the pin numbers using HDAPatcher and came up with this:

 

Back Mic: 9 34 24

Line In : 8 35 26

Speaker : 20 12 2

LineOut 1: 21 13 3

Headphone: 27 38 37

 

Still no luck, I can't get osx to recognize the sound card (I'm using HDAEnabler.kext with AppleHDA.kext). I think the problem may be in the controler.plist that I have to edit but I'm not sure.

 

Thanks for all the wonderful help so far, it's greatly appreciated!

OK: this is interesting. I did a codec dump of the ALC889A on my system using Taruga's latest HDAudio.kext (run at boot) and this is what comes up:

 

Vendor Id: 0x10ec0885

...which according to the codec.rtf MadTux provided is already covered by the 10.5.5 AppleHDA.kext. I also looked in the info.plist using HexEdit and "885" seems to be there many times.

 

So what's missing? Why isn't the system recognizing this codec? And more importantly, how should I handle this next?

 

I've included the dump below if anyone cares to look. Thanks!

Thanks for your tips MadTux, now my question is when you mention about

"And U have to use HDAEneabler or EFI string for your HDA to load"

 

So if I edit the plist file in AppleHDA.kext it won't make it to work just with that?

 

Why and what do we have to add to the EFI string?

I think the easiest way is to use AppleHDA patcher from Taruga

Yes I agree. But I suspect that Taruga's patcher does much of what this thread shows us how to do manually. I think it's a good idea to learn to fish rather than depend on the fisherman.

 

Also, one issue with Taruga's 1.20 AppleHDA patcher (there is a 2.0 but there's no release date) is that it produces an out-of-spec AppleHDA.kext, whose internal version is 1.2.4 whereas the 10.5.5 AppleHDA.kext is at 1.5.7 and seems to have quite a few internal changes. Plus on my system the 1.20 patching does work, but one of the outputs is wrong. Another advantage of meddling directly in the configuration is assigning inputs and outputs the way we want them.

 

And then of course, there's the aspect of discovering OS X's intricacies. Like MadTux said: "Learn and stuff..."

Limini, I believe your card is already patched, yust look around to find a kext. I think this is one of best suported audio cards here.

Me too I think MadTux did a great job explaining us how to do it using the latest kext, with taruga's patcher you were locked to 10.5.2 kexts but with this method you can do it by yourself and patch newer AppleHDA.kexts (10.5.6 in the future) and voiding those non sleep, non wake ups, etc.

In principle, Taruga's 885-889 for Leo works, but only ONCE. On first reboot, all the right info is there in Preferences and all the I/O works. But on 2nd reboot this card disappears and the System Profiler information for it too. No one here, or on Taruga's forum, has an explanation for this behavior. And it seems I'm not the only one this is happening to. A codec dump into Taruga's 1.20 patcher also works, but the information in the outputs is innaccurate, and this patcher creates an older version of AppleHDA.kext. So I'm looking at your method as an alternative, and hopefully more long term, solution.

U may try this, it could be a good start

And I think that pins from patcher are not innaccurate, just sometimes they dont work like they should :-)

hi im on a pavillion laptop with IDT audio codec and I cant get osx to recognise my audio . Ive patched everything what could i be doing wrong??

Thanks, MadTux! I'm now trying to use EFI to load the driver. Does this tutorial cover what I need to know?

Yes that is a great one. But it is easier to use EFI STUDIO, has everything "built in" Network, Audio, Graphics.

MadTux! MadTux!! It WORKS! Many , many thanks! I used your kext + HDAEnabler and the settings survive multiple reboots. All the Mac related I/O shows up properly and Built-in Speakers, and Digital out work. I haven't tested the inputs yet, but they're there. I found the bass anemic on the "Built-in Speakers" which is my Line out and looking through the plists I found where soft DSP is applying equalization to both the Built-in speakers and to the Mic. I'm going to try to remap the outputs so that I can get Line out signal to come out from the green jack line out; there are in fact 5 analog outs, 2 line ins, 2 mic ins and SPDIF I/O on this codec, so it should be possible to reroute. Is it possible to add I/O that isn't typically on a mac?

 

So now that it's working I guess I can try using EFI Studio and getting rid of HDAEnabler. I find it funny that looking for information on how to use EFI Studio to generate strings I find informations like "...then just use EFI Studio to input the right string for your graphics and audio, and you're done." Great... 2 questions:

 

1. I've found one with my graphics card as a preset, so I guess all I have to do is select my graphic card and "HDEF" for the audio and write both to the Boot.plist. I read on a thread here that you have to write both at the same time. If I already have my graphics string in Boot.plist, will EFI Studio replace the old one with the new or should I clean the old one out manually?

 

2. Do I need to fiddle with the HDEF values or can I assume EFI Studio is getting it right?

 

You do realize that by helping me out you've compromised my education...

[Cheops]

Would this method work getting my internal subwoofer working on my acer laptop for the ALC268 codec?

 

Thanks

 

Ade.

I don't know, I am not an expert. People U have to try by your one. Test, learn...

EFI_STUDIO replaces with new string, you don't have to delete manualy. I suggest U to put all three stuff in a same time. Network, Audio, Graphic Card in no particular order

 

2. Do I need to fiddle with the HDEF values or can I assume EFI Studio is getting it right?

If it founds HDEF it will put correct values, same thing for AZAL

 

P.S. And google is your friend and best educator.

Hey I'm stuck at finding out my nodes.

Because the first node has only 1 Connection, and it's not marked with a star.

I also tried Taruga patcher to find them out but this didn't work as well.

Even the repalcement of alc268 with alc885 as recommended on page 1 didn't work.

I attached my ubuntu linux dump. Could please someone help me?
