[ref]Mirone[/ref], thanks again for reply. Unfortunately it didnt fixed the issue. When I open Audio MIDI Setup or System Preferences -> Sound, there are still no devices at all. Do you have any other ideas to try?
(FYI: I copied aDummyHDA.kext to S/L/E, I have original AppleHDA.kext in S/L/E, there are not any other audio kexts //AppleALC, VoodooHDA, …// in S/L/E or L/E, there are no audio kexts in EFI/CLOVER/kexts and I always repaired permissions and rebuilt caches after copying kexts using Olarila Repair Permissions)
