By far the easiest way is to use an application.  Have your virtual
audio device ship the data to an application, which then forwards it to
another audio device.

But, in that case, what's the point?

I think you'll find that, if you add the lines to that INF file to
register your APO, an FxProperties page will appear.

I think you misunderstood.  The "V" in AEVAD stands for "virtual".  It
IS a virtual driver.  In the past, I've advised people that it was
impossible to create a virtual WaveRT driver, but AEVAD stands as
evidence to the contrary.
