Hi,
Thanks. I have few questions :
1. How to reroute the audio from virtual audio driver to a physical audio
device? Is there any registration or something required to be done here for
that specific audio device?
2. If I succeed in rerouting the audio, I still need to register my custom
sAPO for system effects. Is there any workaround to register sAPO to
Wave-Cyclic Driver which does not have any FxProperties? Also, as suggested by
some replies in this thread, Microsoft AEVAD cannot be used to create a
virtual driver.
Again, any pointer to an alternate/better approach will also be helpful.
Thanks and Regards,
Vinayak S

Hi,
You cannot hear anything because the VAD is not linked to any hardware audio
device. You need to reroute the audio from the VAD to a physical audio device.
I am not sure about this, but I think that we cannot add FxProperties to this
MSVAD because it is a WaveCyclic Driver. Perhaps It would be possible with the
new sample from Microsoft AEVAD (
http://code.msdn.microsoft.com/windowshardware/audio-engine-virtual-audio-174876a3 ;),
which is a WaveRT Driver.
Best,
M'hand.
