Realtek High-Definition Audio Device vs Realtek Audio

When I go to Device Manager > Sound Video and Game controllers my Dell XPS 8940 has the Realtek Audio driver (version 6.0.9228.1, 8/24/2021) installed. If I click Update driver > Browse my computer for Drivers > Let me pick from a list . . ., two "models" are listed under compatible hardware: High Definition Audio Device (HDAD) and Realtek Audio. When I try to use the HDAD, Windows (11) warns me that "Installing this driver is not recommended because Windows cannot verify that it is compatible with your hardware. Et cetera.

Do I NOT have an HDAD in my computer?

 

Suggestion for audio troubleshooter

Recently I had a problem with the audio output on my computer, and the troubleshooter couldn't solve it. It suggested that I reinstall the Realtek driver, which seemed to work for a short period sometimes, but then the problem returned. I seem to have
found a better fix: reinstall the Intel(R) Display Audio. Maybe the audio troubleshooter should be revised to suggest that as a possible solution to audio issues. Does that possibility make sense?

 

Realtek Audio issue

Thanks so much for your response Fireberd.
Yes, I see where you're going. The HDMI that is functional is on the AMD Radeon card. The HDMI on the integrated panel is NOT functional which I just checked after receiving your response. I've pasted here the rear panel of the 8100 with respective ports. So neither audio or video are working on the integrated ports but the USB's are. I'm still wondering if this isn't a Realtek audio driver issue because while the current driver displays the 5.1 audio option in <Sound> it doesn't display the optical audio option for the rear panel port yet another Realtek driver I tried displayed the optical port but not the 5.1 option so it seems like I'm just not getting it right with the Realtek drivers I tried. Granted, a Realtek driver isn't going to resolve the integrated video issues but that may be a whole different driver issue just as the USB's are working on different support. Been on the Dell site many times but other than the Realtek driver I have installed I can't find any other audio drivers listed. Going to see if there's a Dell forum I can post to. I know other end users have upgraded this MB to Win10 and supposedly it's 100% functional. Thanks again for your response, let me know if you have any other suggestions!
