This bug is not really a duplicate of #1261666 because all that one
fixed was the compiling with webrtc part. Pulseaudio in 16.04 is still
not configured by default to enable echo cancellation and just doing the
changes to /etc/pulse/default.pa doesn't seem to work as the module
fails to load complaining about configuration settings. It would be very
nice if this was just a regular part of the distribution and enabled by
default out of the box.

Title:
pulseaudio should be compiled by default with noice cancelling and
echo reduction
Status in pulseaudio package in Ubuntu:
Confirmed
Bug description:
In other OSs either the system itself or the sound drivers provide
settings to enable noise reduction and echo cancellation. However in
pulseaudio it has to be manually compiled in.
It's a feature that should be a standard, and don't come with such a
pain to enable, as I believe it would of very useful to provide by
default.
To implement this a dependency to Webrtc library should be added, as
well as a couple of configuration lines:
In debian/rules file, go to ~line 57 and add "--enable-webrtc-aec" to
DEB_CONFIGURE_EXTRA_FLAGS (say after the --disable-hal-compat option)
In debian/pulseaudio.install file and add: usr/lib/pulse-*/modules
/libwebrtc-util.so
Enable webrtc plugin in /etc/pulse/default.pa: sudo gedit
/etc/pulse/default.pa
### Load echo cancellation module
load-module module-echo-cancel source_name=echosource aec_method=webrtc
set-default-source echosource
