DarkAlex97 Posted December 29, 2019 Share Posted December 29, 2019 Hi guys i just installed Catalina using Open Core. Everything is working except audio. I tried to install the os multiple times chaning some parameters but nothing. I followed this guide: https://khronokernel-2.gitbook.io/opencore-vanilla-desktop-guide/ I'm pretty sure the problem is here: Maybe i'm setting a wrong layout-id? Am i missing something? I tried different layouts (1 and 11) (the one in the picture above is 11) https://github.com/acidanthera/applealc/wiki/supported-codecs Here's the content of the USB: And here's the config.plist i'm using https://pastebin.com/2QBpqafb My hardware: CPU: intel i7 8700k GPU: integrated intel hd630 RAM: Corsair ddr4 16GB (2x8) Motherboard: ASUS ROG Strix Z370-E -> Audio: Realtek S1220A Any help is much appreciated :3 Link to comment Share on other sites More sharing options...

Are you sure your HDEF (or whatever name) audio device is located at 0x0b, not 0x1b ? Is there a way to try other layouts without reinstalling the OS from scratch? Also i'm not sure about the 0x0b, how can i check it out? Does gfxutil -f HDEF works also if audio is not working? Sorry but i'm kinda a noob Edited December 29, 2019 by DarkAlex97 Link to comment Share on other sites More sharing options...
DarkAlex97 Posted December 29, 2019 Author Share Posted December 29, 2019 (edited) Where i can find the config file? Here's what i found about HDEF in the register and here's the output from the terminal I also attached the ioreg output iMac di Alessandro.ioreg As for the DSDTs i used mine without modification generated with SSDTTime And these two https://github.com/acidanthera/OpenCorePkg/blob/master/Docs/AcpiSamples/SSDT-PLUG.dsl https://github.com/acidanthera/OpenCorePkg/blob/master/Docs/AcpiSamples/SSDT-EC-USBX.dsl compiled with MaciASL Edited December 29, 2019 by DarkAlex97 Link to comment Share on other sites More sharing options...

I'm having the same issue with similar specs. Not sure where to look or what to change on the config.plist Link to comment Share on other sites More sharing options...
