Audio always worked here with all methods I tried :D

I mean that you should not touch AppleHDA.kext if possible.

Ok, you have /System/Library/Origin/AppleHDA.kext with correct permissions.... but should be in /System/library/Extensions/ only (with correct permissions) otherwise will never be loaded, not by OSX .. not by any known bootloaders. When in the correct place with permissions repaired, you have to rebuild the cache so if you boot with the prelinkedkernel AppleHDA will be loaded (not otherwise).

I know this. I'm just saying that I got the original one and if you got some new methods I'd be willing to try them (in a single reboot).

Ok. 

Looking better at your ioreg I can now see that AppleALC is loaded, so you have to use only one method. With more than one method (as you demostrated here:             #370            ) I'm sure that will not work and no one can help you, sorry (is not possible :( ).

"more than one method"? 2.ioreg is ALC with original HDA. 3.ioreg is patched HDA without ALC.

Are you saying that my laptop could only use VoodooHDA?

normally AppleHDA print all the ids in ioreg (IOHDACodecDevice) even if not working (as in a fresh installation), so it comes to mind that you have not vanilla files, but if not as is, you have some problems. Then I Can't say witch... BTW once I see this section empty with bad bios settings

2. A aDummyHDA.kext usable with Clover (need KextsToPatch to works for unsupported codecs).This leave AppleHDA.kext totally untouched!

Comes the doubt. And Mirone said use a "botched AppleHDA".

I didn't add KextsToPatch, and still not working.

 

you are connecting your notebook to
an external monitor?
I suggest you do a new installation,

confirms that you have no AppleHDADisabler installed.

Why reinstalling? This is not Windows))) kextstat in terminal would be enough to see if AppleHDADisabler exists... Ioreg also shows AppleHDADisabler. My opinion he have to try inject HDA properties through custom DSDT. 

@I2dy: Can u give your clean ACPI Tables (F4 in Clover GUI) from EFI/Clover/ACPI/Origin (I need whole folder Origin) .

Yes, I'm using an external monitor. I did a new installation yesterday and didn't install VoodooHDA or any Disabler since.

aml files in OEM folder. These are from Linux.

Hi Mate,

 

I checked your DSDT and patched it for:

- Onboard Audio with Layout-ID 3 (hopefully)

- HDMI Audio

- Battery Management (use ACPIBatteryManager.kext)

- Inject LAN and WIFI

- Prepare USB for ElCapitan

- Add DTGP-Function

and some small stuff more...

 

This means you should not use any DSDT-Patches in Clover, since all the necessary stuff should be in the DSDT.aml file

DSDT.aml.zip

I got this ioreg only once. Haven't got it since a reboot after it. Didn't change ACPI/patched directory or config.plist, tried to rebuild kernel cache. I have no idea why it worked and stopped working...

Where did you put the AppleALC.kext?

/EFI/CLOVER/kexts/"YourOSXVersion" or /System/Library/Extensions?

 

If in Clover, what is written in the "SystemParameters"-key of you config.plist?

<key>InjectKexts</key>
<string>Detect</string>

or 

<key>InjectKexts</key>
<string>Yes</string>

First, DSDT patches aren't working for me as log says "kernel[0]: AppleALC: (DEBUG) util @ getOSData layout-id was not found".

 

Second, I think I've found one of the problems. In "AppleALC/kern_resources.cpp", the last few lines got an array of ControllerModInfo. And there isn't one for my laptop.

I see...

Somehow I injected the HD4600 for Desktops not for Laptops...

 

I corrected this in attached DSDT... Sorry... :)

5/9/16 7:09:09.000 AM kernel[0]: AppleALC: (DEBUG) util @ getOSData layout-id was not found
5/9/16 7:09:09.000 AM kernel[0]: AppleALC: alc @ layout-id was not provided by controller at HDEF

This is why I wanted to use Clover to do layout-id injection. I'm sticking to Clover on this now.

 

Also, since no ControllerMod for my laptop (0x8086, 0x8C20) exists, I think AppleALC's code needs to be changed before I can continue trying it.

Do not attempt to explain things you do not understand. Controller mods may not exist if no modifications are meant to be done for a certain controller.

Okay, I got it, the message "missing ControllerModInfo for 0u controller" is harmless. I reinstalled the system, don't have DSDT.aml in ACPI/patched, have DropOEM_DSM/HDA set to true, Audio/Inject set to 3, log tells me so too and so on. But I'm still getting "failed to find a suitable codec, we have nothing to do" for the Conexant CX20757, what to do now?

Correct

Well, I guess you should now choose/write/create the necessary resources for your codec?

You could paste the log here just in case something indeed went wrong.

Hi vit9696 and Insanely Crew,

 

What an amazing project ! Bravo !

 

I have a Gigabyte GA-Z170X Gaming7 MB. with a Creative Labs SC inside: CA0132.  I'm using a patched AppleHDA,kext ( with layout-ID = 1 ) that's working like a charm.

 

I need to run the patch on the fly from Clover to get an Apple Update proof driver.

 

I have attached the needed files I know about from the AppleALC Wiki. ( and the patched AppleHDA)

 

Just tell me if there is something missing, I'll add it.

 

Can you help me to make my ca0132 working ?

 

Thanks alot guys

Hi, yassinex. Thanks for your kind words. Creative audio and many other codecs would be nice to have supported.

———

Unfortunately audio edits are not my specialty, and I am mostly working on other projects at the moment. I do have time to merge a pull-request and I likely will deal with AppleALC bugs, but I may not dig into users' resources, sorry.

Fortunately there are enthusiasts who maintain AppleALC, all from applelife ;p, in particular vandroiy2012 who answers in the topic. If you beg him he might help in case he has free time. Otherwise you could read the wiki in more detail and get your data work after trial and error.

 

This is addressed to all those who need help.
