How can I programatically set those sound effects available from the Windows Speaker Settings (Enhancements tab)?
回答1:
I am afraid of that this is not possible. See the comment of Maurits on his blog.
Each endpoint has two property stores; the "endpoint property store" displayed above, and the "effects property store." The endpoint property store is exposed to applications, but the effects property store is limited to:
1) the audio driver
2) the audio engine
3) the Sound control panel.
So only the user can view / change settings in the effects property store, and that only through the Sound control panel.
