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? > 2.

I think you'll find that, if you add the lines to that INF file to register your APO, an FxProperties page will appear. > Also, as suggested by some replies in this thread, Microsoft AEVAD > cannot be used to create a virtual driver. I think you misunderstood. The "V" in AEVAD stands for "virtual". It IS a virtual driver.
