Which audio layout for my alc1220? Speakers aren't working

Hello,

I've got a Gigabyte z370 gaming 7 which has ALC1220 on it. With Clover I've got AppleALC loaded with layout 11, and I get sound but only when plugged into the wrong port on my mobo's backplate.

On windows and with the manual, I've verified my stereo speakers are hooked up correctly in the line-out/headphone jack.

On 10.13.1 - The only way I can get audio to my speakers is to plug into the rear jack instead. Which means audio works fine in OSX, but not in windows when I dual boot.

I also do not see an "internal" speakers option in my osx sound panel.
