When I sometimes loose audio on my U330P and have to boote without cache that option dosn´t exist in newer Clover build.
Just updated to 4061.
But there´s an option called "Debug kexts (kextlog=0xffff)"
I used that and my audio came back without using the
sudo touch /System/Library/Extensions && sudo kextcache -u /
in terminal.
Is that just a coincidence ?

You can boot without caches with kernel flag "-f".

Yeah I know but on older Clover versions it was in the menu.
I can provokate audio to stop working by using one of the F4 -F10 keys (Elan)
Reboot and audio is gone.
Rebot using the debug kext option and audio is back.
I did it 4 times succesfully.
So I think it´s much easyer instead of reboot without cache and then run the kext cache command and then reboot again.
If some of you loose audio then try this methode and check if it work for you

Yes. It was removed... now you have to specify the kernel flag manually.

I have no ELAN hardware and the ELAN kext is not open source (in contravention of the APSL license).

You should see if pre-patch_hda.sh will help with your audio stability problem.
It is in the probook github.

It´s not a big problem for me but do you have any idea why it´s working ?

No idea. No interest either... (I use pre-patch_hda.sh and "-f" when needed).

Ok never mind.
I just thought that if you loose audio as you indicate you also do sometimes by writing and "-f" when needed
This could make it easier.

I think you will lose audio less often if you use pre-patch_hda.sh.
And if you do, advice remains the same: boot without caches, rebuild cache, reboot.

If I´m going to use your pre-patch_hda.sh. i gues i have to delete all AppleHDA entrys in config.plist/KextToPatch
and install original AppleHDA to S/L/E. before I execute pre-patch_hda.sh.
Is that correct ?

No.
Just run it with your current config.plist (the script applies the patches from config.plist to AppleHDA binary).
Read the Probook guide for any questions about its use.
