[Guide] Intel IGPU HDMI/DP audio (all Sandy Bridge -> Kaby Lake [and likely later])

Yes. Lesson learned on that one.
Ah I figured it was time for a fresh start anyway.
 
Hi RehabMan,
Can both hdmi audio and onboard audio coexist? So I can switch line-out device in control panel.
 
hi, I have had onboard audio work, after follow the guider install some hdmi audio support , none is work.
I checked each point you mentioned, all is right, but no sound!
please help me ..

Your ioreg indicates audio is working.
Your profile does not indicate you own a laptop.

yes. I final found this mistake.
I have compile a piece of hotpatch in project OS-X-Clover-Laptop-Config, and forgot change some define value in SSDT-Config.dsl.
Now I have modified those value to compile desktop version...but still got not sound.

There are other guides for desktops. I don't want to get into troubleshooting desktops in the laptop forums...

you need to upload your "Problem Reporting" files (see post 1) so we can see what is happening :)
