Patch AppleHDA kext on-the-fly with Clover bootloader

[RehabMan]

i absolutely don't know how to modify your Apple HDA injector script to work with CX20590

There is only one line that needs to change in the script:

codec=ALC283

To:

codec=CX20590

That affects the name of the injector....

The rest of the script is data driven from files in Resources subdirectory.

oh ok thanks i'll give it a try

oh ok thanks i'll give it a try

If you understand what is going on here, you should recognize the contents of the files in Resources...

yes that's right thanks!
but then i will ned another ahhcd.plist with other codec id right?

where do i get these things for cx20590?

<key>CodecID</key>
<integer>283902595</integer>
<key>ConfigData</key>

Ok, you really shouldn't be asking this question at this point, as you already needed to do this to create your own injector.

That data comes from patched AppleHDA.kext/Contents/PlugIns/AppleHDAHardwareConfigDriver.kext/Contents/Info.plist. It is specific to your codec. Same goes for the files in Resources/layout... Platforms.xml.zlib and layout*.xml.zlib, both specific to your codec.

thanks! layout is mine specific!
the other thing i have to change

is this correct like this?

EDIT: i changed layout and platforms and also the specific data in ahhcd.plist
but when i start the script it always says:

Creating AppleHDA injector for CX20590...cp: ./Resources/layout/*.zlib: No such file or directory
Merge: Error Reading File: ./Resources/ahhcd.plist
Done.

EDIT: I DID IT I got the AppleHDA_CX20590.kext should this kext now in S/L/E or in the Clover EFI?

in S/L/E. Clover folder only work when booot without cache.

AppeHDA_CX20590.kext at S/L/E won't be loaded at boot i booted with -s and load the kext manually but nothing changed.. kext won't load..

It is an injector kext. It doesn't really "load", but rather contributes an IOKitPersonality for things that do actually load (AppleHDA.kext and AppleHDAHardwareConfigDriver.kext).

It will show as Loaded in System Information:
