Never mind. I’ve done a reasonably vanilla install of High Sierra on Optiplex 7040MT. Sound worked like a charm. Reason to install High Sierra was to make sure my nvidia GTX 1060 works. Wouldn’t have been possible with Mojave or Catalina.All that is described in # 7.
Would this EFI and config.plist work for Catalina? I have the same machine and I'm getting LocHB 71B4903C-14EC-42C4-BDC6-CE1449930E49 error. Any idea how to resolve this?
solutionI've done like you write but the problem in starting installation still remain.
Can you tell me your BIOS configuration? Maybe the problem is there...
Forgive my English.
Mac Osx Catalina 10.15.4 clean installation, everything working correctly.
