Did you try removing the AppleALC.kext completely to see if that is indeed causing the issue?
Remember AppleALC.kext needs to be installed simultaneously with the latest Lilu.kext using kext installer to L/E in order to function properly.
You have a lot of unnecessary kexts in your Clover/Kexts folder. Only Clover/Kexts/Other folder should exist - all other folders - 10.11, 10.12, 10.13, etc - should be deleted. Once you install all kexts to Library/Extensions using kext installer, only essential kexts (FakeSMC/VirtualSMC, Lilu, Whatevergreen, usbinjectall, etc) should be kept in Clover/kexts/other and in config.plist "System Parameters" - "Inject Kexts" should be set to "Detect".
Also most users report having more success using VirtualSMC in Catalina instead of FakeSMC.
