[Solved] ASRock z370m pro4 - no sound device(output)

[mactestgood]

Completely followed this top menu Guide: https://www.tonymacx86.com/threads/...sierra-on-any-supported-intel-based-pc.235474

Everything work except sound. "system preference -> Sound -> Output" is empty.

What I have tried:

After installation, install only "quick start" from Multibest. Then restart from hard drive, then install Audio drive "ALC892" and restart. not work.

Then install "200 / 300 Series /X299 Audio Device ID Patch" and restart. not work.

Then install "ALC892" again and restart. not work.

What else I should do?

Already tried but not work. I guess it was the macos version(10.13.5). I saw the same motherboard success story here with older version(10.13.3). But seems it's impossible to download older version.

Not what Post #1 says, missed a selection; audio fail.

guess it was the macos version(10.13.5). I saw the same motherboard success story here with older version(10.13.3)

High Sierra version is not relevant.

Finally solved!
I installed macos 10.13.3.
Then in multibeast, enable "100/200/300 series.." and "200/z370 series/x299..", restart.
Then in multibeast, enable "alc 892" and "optional 3 port(5.1)", restart.
Audio working now!

I don't know why, but in macos 10.13.5, I tried many many guides (including above), just don't work.

How to install 10.13.3?
I downloaded a 10.13.3 DMG from internet, double click get a 10.13.3 install APP. But failed create boot usb using Unibeast. So I tried this guide: https://www.tonymacx86.com/threads/how-to-create-a-macos-mojave-public-beta-installation-usb.254626/ and it works. (note: usb better insert to 2.0 when booting)
