hdmi without sound in realtek 1150 - gigabyte z97x-gaming 5

[MARTINI1]

I installed High Sierra in a friend's computer with i5-4690K (intel hd4600) in motherboard gigabyte z97x-gaming 5 (intel gen 9 chipset) and the hdmi sound I have not been able to make it work with lots of tests, using the clover config of rehabman, the patches of toleda or add hdmi and the useintelhdmi in clover but without any result

and I searched for solutions and tried and nothing, I do not know what I'm wrong about

all other sounds work, audio jack and optical output
