no audio on ASUS Prime B350-PLUS motherboard

[diego-ch]

I'm running the same motherboard and cpu,
but get no audio from the motherboard with this config.

CPU: AMD Ryzen 7 1700
MOBO: Asus Prime B350-PLUS / BIOS Version: 5602
GPU: NVIDIA GT 710 2GB and NVIDIA GTX 1080 (Disabled via SSDT)

can you confirm motherboard audio works for you?
besides that, HDMI audio and GPU HW Acceleration works fine for me.

I don't use analog output from motherboard, so I can't test it now, but macOS detect outputs correctly

I've been trying to figure out why it doesn't even show up on macOS for me,
so far i've noticed that it shows up as AZAL instead of HDEF, maybe that's my issue.
on the bios i have it set to HD audio instead of AC97.

what bios version are you running ?
could you check the output of gfxutil on your system to see if it's the same?

It looks there's no AZAL, I have only HDEF

I tried renaming ACPI AZAL with HDEF, but no luck,
so i ended up replacing AppleALC with VoodooHDA and it's working now.
The only downside is that it shows all my HDMI/DisplayPorts as connected (even the ones on the disabled gpu).
I assume our boards must have a slight difference or it could be different bios versions.
