So for your Vista implementation you were able to use a LFX APO for the render
side that feeds render data to the AEC which lives in the WDM filter driver on
capture side. Did you have a problems with render/capture synchronization as
we've been discusing with the GFX/LFX approach? Did you make any attempts to
pursue a GFX/LFX framework for AEC as we've been discussing?
thanks.

sorry i misunderstood your current approach now, so you have ditched the
LFX/GFX approach and have not gone to a DMO approach for you client or is it
the other way around.
My client owns the microphone hardware, and it uses an XP-style driver, so we
have a standard WDM filter driver on the microphone end, and an LFX APO on the
speaker end. For pre-Vista systems, we use a filter driver on both ends.
