HDMI audio doesn't work with intel HD graphics 630 in Catalina 10.15.4

this is my low cost build:
CPU: Intel Core i3-7100 3.9GHz 3MB
MB: Gigabyte GA-H110M-S2H
Internal GPU: Intel HD Graphics 630 7 MB
NO dedicated GPU

i instal macOS Catalina 10.15.4 and everything work (maybe).
But I connect a samsung monitor (I use HDMI-HDMi cable) and the computer doesn't see the HDMI monitor, so I can't use HDMI audio...
