Soterlll Posted February 28, 2024 Share Posted February 28, 2024 I am using modified Herve's EFI and everything works fine except this problem: Sometimes there is no sound. Sleep/Wake or Reboot helps to restore sound. Tried everything, but the problem persists. Lilu+AppleALC debug report and EFI(ACPI, config, kexts) attached. Specs: Dell Latitude E6530 with A22 Bios i7-3740QM 1366x768 screen 16GB RAM HD 4000 + NVS 5200M(disabled in SSDT-DGPU) Monterey 12.7.3 report.zip EFI.rar Link to comment Share on other sites More sharing options...
Administrators Hervé Posted February 28, 2024 Administrators Share Posted February 28, 2024 Hi. I’ve encountered this behaviour on all my recent Dell Hackintosh laptops. Never found a fix. Initiating sleep and interrupting it by an action like moving the mouse fixes it. Possibly an IRQ or HPET-related matter. Link to comment Share on other sites More sharing options...
Soterlll Posted March 2, 2024 Author Share Posted March 2, 2024 It seems switching Serial Port to COM2 and using original DSDT without any patches solves the problem. Link to comment Share on other sites More sharing options...

Soterlll Posted March 4, 2024 Author Share Posted March 4, 2024 After some additional testing this method also didn't help solving this issue Link to comment Share on other sites More sharing options...
