Hello,
I had the same problem but I think I got the reason behind it.
Your Lenovo PC comes with
| Audio | JBL^®^ Stereo Speakers with Dolby^®^ Audio Premium |
|---|
so the updated audio driver in your PC disables the spatial sound.
When you check the speaker properties you can see JBL tab in it (HARMAN in my case, Lenovo Ideapad 510).
If you want the spacial sound in your PC, you will have to roll back your driver to the oldest version i.e without audio driver update.
But I think the default provider in Lenovo PCs, JBL in your case, is also good.
