Ok so I tested with the new code, same result- frame size=
160, filter length=160 ms/1280 samples, 8000 Hz
diverged after 9564 calls/packets or 191 seconds. My system
stays relatively in synch but is not perfect- difficult to measure
if there is any clock drift, but it probably is.
In order to make it break faster I use an open air usb microphone
that is part of a logitech notebook camera, and then plug headphones
into the speaker jack (sensitive mic can pick this up).
I am not saying this is a *fair* test... :) It takes longer to
cause this bug if everything is open air.
