They start about 1 second apart. The signal does not repeat usually, so it is hard/impossible to capture it. I have looked at all the sound configurations I can find and played them all but it's not listed there. (system, growl etc) Has anyone heard this before? Is there maybe a database somewhere that contains sounds not only to listen to but also by some form of description to that one have a change of identifying such a sound one has no recording or such of? thanks
