There is a script in my hack-tools project on github that will create LiluFriend.kext automatically (and correctly).

Can you tell me what the problem with my script is?

Maybe nothing... I didn't really look at it as far as this thread (would require more debugging info from the script and some info about what kexts are installed).

This particular user seems to have a botched setup.

The ioreg you attached shows audio working.

Note: You forgot to remove ForceKextsToLoad from your config.plist (as written in the guide).

Ok did it and rebooted, no audio again. (as i said happens 50% of times and not if i inject it with clover)

It probably is a timing issue in AppleALC.
I think it is trying to scan ioreg for HDA controllers too soon, and sometimes they are not fully populated.
A well placed IOSleep in AppleHDA might help.

For example, right here in kern_alc.cpp:

Code:

void AlcEnabler::updateProperties() {
   IOSleep(250); // patience grasshopper, patience...
   auto devInfo = DeviceInfo::create();
   if (devInfo) {
...

Thanks but i dont know how/where to place the code. Should i download the source from github and edit the kern_alc.cpp?

Clone the repo. Make sure you can build it as is (read the README/wiki). Then make your modification in Xcode. Then build the modified version. Hopefully, you have some programming experience and some knowledge of Xcode.

Did it and right now, in 4 boots, 1 was without audio. Maybe clover injection is a better solution in my case?

Make sure debug version of Lilu and AppleALC are installed, and -liludbgall kernel flag is used.
Attach PR files from both working and non-working boot.

And... sounds like an improvement with the delay, no? Perhaps a larger delay will help...

Ok here the files. Yeah, maybe next ill try to use a larger delay

Note different PCI data enumeration in the logs.

Something like this in Lilu may help make it easier to try different values of delay after IOPCIConfigured:
