How do i fix no audio device installed in windows 11?

What's wrong seems to be that you made the mistake of accepting Microsoft's relentless nagging to convert your OS from Windows 10 to Windows 11, which is obviously not designed to work with older hardware with older audio parameters. MS is telling people to go buy a new computer with an upgraded intel chip that Win 11 was written to work with. Aint that nice.

I have a new (12/2023) Dell XPSi7 with Win 11 pre-installed and the latest RealTek and NVidia cards and drivers. And I'm suddenly getting the same message: "No audio device is installed." So the problem lies elsewhere....but where?

"Smart Sound Technology" is not in the vocabulary of my cheap computer nor the inexpensive Roku TV that I was feeding sound thru. Ironically, the visual part of the interface between cheap computer and cheap TV continues in my situation without fault, but not the sound.

And as someone else recently pointed out, the problem happened when I foolishly upgraded from Win10 to Win11, so it was definitely caused by a destructive Windows OS change imposed by Microsoft, nothing else. So, Microsoft needs to fix it, not hardware manufacturers.

I suppose that some people are getting around this problem because they have different hardware/software combinations that the demons of Redmond provided for in their creation of the Win11 Frankenstein monster but I can't imagine what multitude of people at the lower end of the economic scale have been devastated by MS' totally irresponsible approach of ignoring many computer configurations. I still suspect it was a marketing strategy to push people into buying new equipment with new software and/or pay $$$ to access MS support, which may not be any better than what you see on these web sites.

I didn't have a screen shot, I replied to someone else's post. Did you try this driver? Intel Smart Sound Technology OED (version 10.23.0.4880) That is what did the trick. I have an HP Spectre that was running Windows 10 when I bought it years ago and upgraded to 11 without problem. My issue happened when I updated drivers.

****?!!!! More reasons to go Mac. I wonder if your new HP was really pre-loaded with Win10 but someone somewhere upgraded it to Win11? Just guessing as nothing from Microsoft makes sense any more (if it ever did). If you ever resolve the problem without returning the computer for refund, please advise as I am still one computer short of sound and absolutely nothing posted in any of these communities has fixed it.
