Hey, I have installed Catalina on my Lenovo Ideapad-520 and tried to use AppleALC for sound. the sound can be played using headphones but no sound is coming through internal speakers. The sound device is Realtek ALC 230 and have tried both the layout ids for the same i.e. 13 and 20 but still the problem persists. I am enclosing my EFI folder as well as a pic of DCPI manager(don't know why but it says codec name as- Realtek(unknown), does that has something to do with this issue? Any help would be really appreciated.My configuration:CPU : Intel Core i5-8250URAM : 8GBGPU : Intel UHD Graphics 620/ NVIDIA GeForce MX150 (Disabled for macOS)Ethernet : Realtek RTL8168GU/8111GUAudio : Realtek ALC230Touchpad : Synaptics Trackpad
