Sorry, only today I was able to return to this problem. 

So, the thing is that the webrtcdsp must be placed in the initial pipeline
("pipe1") because it is the mic from the alsasrc that must "turned of",
i.e., the sound that it captures must be filtered out. These are the full

Remote audio input -> decodebin -> speakers -> mic (alsasrc) -> encode ->
remote audio output

with decodebin stop only established after the webrtc connection.
