volume keys are not working

[a_user1]

i tried to install windows 11 on this device but it's cpu wasn't in the list of approved ones so i did it with workarounds but the function keys and volume keys weren't working on windows 11 you know the button one in revolve 810 those one so i tried to again roll back to windows 10 which settings should have been in it for 10 days but it wasn't so i downloaded an iso file and did it now i am back in windows 10 but my volume keys are still not working

Hi:

Have you tried installing the HP hotkey support driver?

That would be the only suggestion I can offer.

If that works, you can probably reinstall W11 and use the same driver on W11 too.
