Catalina 10.15 Beta - Lost Audio

I need to use Catalina to use new Xcode features. So I risked and updated my:
-Dell Optiplex 9020
-Intel HD 4670
-i5 4th generation

All works awesome, all USB ports, internet, etc. but lost my audio

MultiBeast + Clover 4920 (with the newest stable 4934 I am loosing boot options).
AppleALC 1.37
Inject ID 13 (like for Optiplex 9020)

Any idea how to fix it?

My audio comes via monitor speakers (system threat it like intel audio speakers).

I see on github, there is no kext build for Catalina...
