AppleALC layout list

The following is an auto-generated list of AppleALC layout IDs available per each codec.

Open the relevant .md file inside the vendor folder (e.g. ALC236 vendor is Realtek)

The following guide will help you light that chonk AppleALC.kext

Requirements

• XCode
• MacKernelSDK

How to proceed

After making sure that AppleALC stock kext works without any additional edit you can light the kext from ~ 3.7MB to 600KB :)

Identify your codec

Do I really need to explain how to identify your codec? If you don't know it, use Hackintool or check your codec dump via OpenCorePkg SysReport feature, like this.

In my case, my audio codec ALC295

Slim that fat boi AppleALC

1. Clone AppleALC and open the source project
2. Remove kern_resources.cpp from $(source)/AppleALC as it contains already compiled resources
3. Remove every codec folder in $(source)/Resources except:
   • the one which name starts with the previously identified codec name (e.g. in my case ALC295)
   • PinConfigs.kext
   • Controllers.plist
   • Kexts.plist
   • Vendors.plist

4. Clone MacKernelSDK onto $(source) with git clone https://github.com/acidanthera/MacKernelSDK.git.
5. Run wget https://raw.githubusercontent.com/acidanthera/Lilu/master/Lilu/Scripts/bootstrap.sh && bash bootstrap.sh onto $(source)
6. Open XCode and build the project with Release configuration using ⇧⌘R and after it finishes building the project, replace the old AppleALC.kext with the newly generated

How to generate every kext with a single codec

Run python3 main.py and see the magic happen. Created kexts will be in Kexts folder
