If there is a pause greater than 1 second, Unity records static
In a new 3.13 Unity install, with CM 3.1(3a) SPD, I notice that any greetings or voicemessages that contain a pause for more than one second have trouble. All of a sudden there is a loud burst of what sounds like static. It happens on internal calls as well as external.
I have disabled VAD and comfort noise...AND the wacky thing is that if I mute when pausing, there is no static. So I don't think it is related to VAD or silencesupression.

This is AGC related and is addressed in 3.1(4). The AGC was always doing it's best to bring the record stream up to the dB level specified and in the case of silense or light static noise it would result in a loud pop effect you mention. In 3.1(4) there were additional AGC settings added that indicated if the record stream was below a specified dB level to leave it alone (-35 by default) and to not try and raise any record stream by more than X dB (10 by default) which helps avoid this problem.
