xConfiguration Audio Input Microphone [1..8] EchoControl Mode
The echo canceller continuously adjusts itself to the audio characteristics of the room and
compensate for any changes it detects in the audio environment. If the changes in the audio
conditions are very significant the echo canceller may take a second or two to re-adjust.
