Echocancellation doesn't always work in Chrome/Chromium browsers

[lukeocodes]

Caused by a user not using peer-devices. Here is the ticket: https://bugs.chromium.org/p/chromium/issues/detail?id=687574 It basically says that the echo cancellation only works for audio that is coming from a peer connection. As soon as it is processed locally by the Web Audio API it will not be considered anymore by the echo cancellation.

Possible fix is to go ahead and volume-down the playback when you start speaking. This will improve the barge-in experience, and possibly duck the playback under the microphones' decibel threshold so it doesn't pick itself up.

Is there a way to fix this and just cancel the echo? Can you just route it through a peer device instead of the Web Audio API?
