And hasn't since the beginning of Windows, I think we need to re-think the idea this is a Windows issue. That is, the PC maker issues drivers, not Microsoft. If you want to think it's a Windows issue, then you will, as far as I can tell never see a fix.
Get back to HP and go over drivers and apps needed for this model.
I have recently installed Windows 10 on my HP Omni 220 PC.
Sadly, there is no sound. The web has many suggestions,and I have tried those which are not too technical. When it comes to registry changes, I leave well alone.
I keep getting a message which says "AMD HDMI output not plugged in". I don't have any external connections. I'm just looking for sound on the computer.
This appears to have been a problem with W10 for many months, yet Microsoft are still churning this out.
