When you record (using pulsesrc in gst it seems) you seem to be
recording from your actual h/w mic, not the virtual echo-cancel mic that
is created when you load module-echo-cancel. Thus you won't get any echo
cancellation at all - you're completely bypassing it! :D

See the reply I sent just a moment ago to Abdul Moiz about this same
topic. Ultimately when recording, load up pavucontrol and move the
recording stream to the echo-cancelling virtual mic.
