solved via AsRock TD, AMD driver update.
Win10 should have had this included. ]]> Fri, 31 Dec 2021 01:57:48 +0000 https://forum.asrock.com/forum_posts.asp?TID=20005&PID=91499&title=b550mhdv-no-hdmi-audio#91499 https://forum.asrock.com/forum_posts.asp?TID=20005&PID=91480&title=b550mhdv-no-hdmi-audio#91480 Author: mygmeelas

addition to post.
after checking what my old MB had with the screen the conclusion is that the B550 HDMI does not know the screen (no com), all is (correct) default and I cannot change it (to worse).
but plans for a new higher res screen is also a nogo in this case.
this means that the HDMI port is useless for what it is intended.

Hi, system:
B550m-HDV, 5600G, 16GB ram and NVME hdd
Windows 10 Pro 21H2 install date 19-12-2021, Build 19044.1415
Bios 1.70, 1.80 and 1.90 tested made no difference.
(idea from https://forum.asrock.com/forum_posts.asp?TID=18426&title=b560mitx-ac-no-hdmi-audio-no-inteldisplayaudio)


I have also no audio with HDMI, if I go to config screen audio I have 4x Digital Audio (HDMI) 3-High Definition Audio Device, all not connected, Yet I read this on the screen connected via HDMI.
On A different MB: sound over HDMI with the screen, I have removed the audio drivers and reinstalled but no luck.
the only audio that works is the 3.5mm jack

any idea to solve this? and get audio over HDMI.
