Fresh Sonoma Install: Working Great! (But No Audio)

Fresh Sonoma Install: Working Great! (But No Audio)

I had Ventura working perfectly with SMBIOS "MacPro7,1", did a fresh install of Sonoma and copied the existing EFI folder, everything works perfectly except I can only get audio from my monitor. This is the only selection for audio output:

My headphones are connected via amp into the aux, as they were before, into the back of the motherboard, and my motherboard is as follows: ASRock Fatal1ty Z270 Gaming-ITX/ac Mini ITX LGA1151 Motherboard

Any ideas how to fix?
