Hi,

I am running Mojave 10.14.4 on a dual (actually triple) boot system (Dell 7577 laptop). Audio on my laptop sometimes work and sometimes it is not detected. Actually AppleHDA and AppleHDAController kexts are loaded but AppleHDAHardwraeConfigDriver is not loaded when Audio doesn't work. I have been doing experiments to observe this problem. Some observations are as follows:

1. I tried installing all 3rd party kexts (like AppleALC, Lilu, etc) in L/E location as normally suggested in the forum, but the problem is identical. Audio is detected sometimes and it is not detected other times when rebooted (very frequent problem).
2. I tried keeping most kexts in EFI/kexts/Others folder too (my current configuration), but ditto problem.
3. I tried setting HPET fix flags in clover, Force HPET (currently unchecked), resetHDA (currently checked) and other related flags, but no improvement
4. I tried removing all AppleHDA kextstopatch lines in config.plist, same problem (currently I restored those patches).
5. I set the layout-id in devices->properties for my layout (13) and I tried to inject this id also in clover configurator, but same problem.
6. This problem normally occurs (may be my observation in wrong) when I plug or unplug charger and then reboot.

I attach herewith two debug files, one when audio is detected and the other when it is not detected. Please help

config.plist:
these needs to be enabled:

Thanks for the reply. For the first part, it is exactly like this in my config.plist. FixHDA is disabled, and rest (mentioned above) are all enabled. To be precise, do I need to enable FixHDA or leave it unchecked?

For the second part, I had all my kexts (including essential kexts like FakeSMC and rest) in L/E just before posting on this thread, but it didn't solve the problem. I have now installed Lilu and AppleALC in L/E as you said again. But previously this had not changed anything and the problem remains the same.
