No audio after changing from iMac14,2 to MacPro5,1

[jjforums]

Hi, I installed macOS Sierra 10.12.5 and used MultiBeast to install ALC888 driver + 3 audio port option, with system option to iMac14,2 and audio worked fine there with this setting. I changed from iMac14,2 to MacPro5,1 to get better performance, but the audio device is not identified anymore.

How could I get audio working while keeping the system option as MacPro5,1?

I thought maybe I should install Mojave already and see if audio works there, but not sure about that. Any suggestions are appreciated.

Thanks in advance.
