My zotac pc has no HDMI port, only DP - yes, I know, he has one HDMI 2.0 port physical, but under macOS and clover he see like DP, so for now I got sound via DP port, stereo or 2.0 surround.
Problem partialy solved :)
BTW - voodoHD.kext must be remove, only appleHD.kext and fakepciintelhdmi.kext...
