No sound. Error message "No audio output device is installed"

[Agent--007]

My HP-Omni came originally installed with Windows 7.  I upgraded to Windows 10 without any problems and it worked fine.  Last week my PC caught a virus so I re-installed Windows 10 using Microsoft's MediaCreationTool_22H2.exe.  When re-installing I chose the option to keep all user accounts, data, and apps.  The reinstall went fine and got rid of the virus.  However, the little speaker icon in the task bar has a little red circle with a white x through it indicating some kind of an error.  If I hover the curso over the icon I get the message "No audio output device is installed".  When I go to Device Manager there is no entry for "Sound, video and game controllers".

The PC comes with the IDT audio codec.

The only suggestion I can offer would be to see if this W10 IDT audio driver from a newer model AIO PC gets the sound to work again.

Tempo High-Definition Audio Driver (Original IDT)

6.10.6504.0

Restart the PC after installing the driver.

Dear Paul,

That worked like a charm!  Thank you so much!

While searching for audio drivers on the internet, I found so many full-blown driver updaters that would update all of the device drivers on my PC.  I didn't need that.  They were from unknown providers, and further, if they just updated existing drivers it wouldn't have helped since there was no audio driver currently on my PC.  Since the driver you provided comes from HP, I knew it was safe.  Once again, thank you so much.
