Each audio application has to add the DMO to their audio graph. It is
Microsoft's current philosophy that each application should be in
complete control of its audio path, so an app should not pay the penalty
for AEC processing unless it specifically wants it.
I'm not saying I agree with that philosophy, and indeed I am working
with one client to do exactly what you describe, but that's what the
Microsoft audio team currently espouses.
