This CL corrects the way that the echo subtractor output is adjusted during the adjustment of the adaptive filter when the analog AGC gain changes. The CL also ensures that the main adaptive filter is not updated when this occurs. Bug: webrtc:9561,chromium:867373 Change-Id: I636f936128f7d9f0d82ca4140b59f148eb35d6a4 Reviewed-on: https://webrtc-review.googlesource.com/90401 Commit-Queue: Per Åhgren <peah@webrtc.org> Reviewed-by: Sam Zackrisson <saza@webrtc.org> Cr-Commit-Position: refs/heads/master@{#24101}
