[Guide] Lenovo ThinkPad T440

[RehabMan]

I installed the ALC3232 kext provided using kext beast in /Library/Extensions. Both times an error message appeared saying that the kext was not installed correctly, kernel panic are constant after that.

See FAQ for correct kext install procedures:

Installed to /Library/Extensions using cp -R to ALC3232.kext, no error message but still no audio.

You're sure it uses layout-id=28 (which is what ioreg proves you're injecting)?

Following Siniki's Guide, in the audio section:

In my guide we will use LayoutID28 which is already injected on SSDT-HDEF & SSDT-HDAU - (for MiniDP Audio)
This kext should work for all the other Thinkpad Laptops that do have ALC3232 (ALC292) Audio Codec.

Following Siniki's Guide, in the audio section:

You should verify by examining the kext (it is covered in my ACPI patching guide).

Note also you must boot without caches, rebuild cache, as per FAQ:

Also...
Your kextcache output proves kexts are not installed correctly.
All kexts you need must be installed to the system volume.

Rebuild cache's is done and installed all kexts to new location. No audio still present, could be a mislabeling of audio device between SSDT's - DSDT?

@Sniki Let me know if you could point me out a guide link or so in order to patch the audio kext from the audio coded in linux. Thank you.

Your kextcache output proves there are no patched AppleHDA components installed.
