Original Question: "Audio issue in Mojave"
I, for the life of me, can’t figure out how to get audio working on my machine. I have a Asus P8H67-M Pro motherboard, which I believe is ALC892 audio. I’ve tried Mojave and Catalina and both run flawlessly on the machine EXCEPT for audio! Any suggestions? I’ve tried audio inject 1,2,3,15,20. I’ve tried AppleALC and also VoodooHDA 🤷♀️
