Now something really
weird has happened!
Apparently, my RealTek audio driver (188.8.131.5290_W8x64_A) actually blocked a lot of the functions of Speakers Properties.
When I installed the driver, it uninstalled and reinstalled. After the first restart, after it uninstalled, Speakers Properties suddenly got a load of new features. After the second restart, when it reinstalled, they disappeared again.
So I just uninstalled the driver manually, and now I've got my new features!
Each tab in Speakers Properties has new functions. Enhancements now has Bass Boost, Virtual Surround, Room Correction, and Loudness Equalization.
However, I still don't have the Environment enhancement. I tried looking for it, actually, and got a very vague description about how it was a feature of win7. I can find that again if need be.
