      I have downloaded pulse audio source code from the link shown below


i have untar the file and have compiled and installed the pulseaudio by
following the steps below:

$;sudo make install

Pulseaudio has been installed and i have started the daemon using

$:pulseaudio --start

I have loaded the echo-cancel module as shown below

$:pactl load-module module-echo-cancel

I have run the CLI and found the echo cancel module loaded as shown below

<< list-modules

 index: 17
    name: <module-echo-cancel>
    argument: <>
    used: 0
    load once: no
        module.author = "Wim Taymans"
        module.description = "Echo Cancelation"
        module.version = "UNKNOWN"

I have connected mono mic to the pc
Now I have run the gstreamer pipeline to test the working of echo cancel

$:gst-launch-0.10 pulsesrc ! pulsesink

I am able to loopback my voice but still , echo is prevalant.
Can you please tell me how to check whether echo canceller has been enabled
or not and if it is not enabled then how to enable and run it.
