Anyone knows how microsoft AEC can deal with mismatches between clocks of capture and render streams?
...ne knows how microsoft AEC do it? This technology is much helpful for us to implement AEC in common PC. We know that most low-cost soundcards have different sample rates in capturing and rendering which prevents LMS based AEC from being used in most computer.

In Windows XP, the clock rate must be matched between the capture and render streams. The AEC system filter implements no mechanism for matching sample rates across devices. ............. In Windows XP SP1, Windows Server 2003, and later, this limitation does not exist. The AEC system f...

About Sampling Rate Correction in acoustic echo cancellation
...big obstacle for us to make an AEC algorithm practical.
I have asked many people for help. It seems impossible to eliminate this offset. Then I found something in microsoft msdn website. It seems microsoft's AEC can deal with different sampling rate.
