Done some research, these Tiny USB sound adapters rely on the the main sound drivers so wouldn't work, but thank you for your suggestion.

Anyone solved the problem in Win 10 of sound being...

DM sound reports no errors - ignore the A11 - that;s the bluetooth speaker which was the last thing I tried

Thank you.

I think its 2019 but may be earlier, as with HP's built for price, the BIOS is pretty basic, can't see any audio setting.

What I do get, hard to explain, on the top left of the is a...

Hence for looking for solution "round" the problem,...

Win 10 20h2 clean re-install doesn't resolve audio driver issue on my HP X360 laptop - also tried troubleshooter, uninstall/reinstall drivers (from Realtek/HP/Microsoft). Issue is with both internal...

Win 10 clean re-install solved the original problem

But why so many issues with 1803?

I have now set the time so that updates are...

Apologies, as I said above, it is not my system that has the problem, but a third parties "single boot" win 10 pro 1803 system post the upgrade - the diagnostics are of that system NOT the multi-boot...
