HDMI audio not working

Hi people, can someone help to put my HDMI sound working?
I already tried different methods and I can't figure a way to fix this problem.

And another question, someone knows why the HDMI port just work if i use macbook pro 14,2 on smbios? Because my hardware is much more similar to 14,3.

My Specs are:



MSI GE62-7RE

Intel 7th Gen Core i7 7700HQ
Intel HD 630 Graphics + Nvidia GTX1050Ti (4GB DDR5)
16 GB DDR4 RAM

thanks in advance
