I tried echo-cancellation with pulseaudio using an ubuntu 13.10 live- session (booting a live-session from usb-stick).
Loading module-echo-cancel without specifying canceller works like expected (propably using speex canceller-implementation; I also verified this by using gstreamer-properties, which echoes back to speaker what is recorded from the mic. Using echo-cancellation will reduce the echo- loop) But specifying canceller 'webrtc' which should be included in pulseaudio since version 2.0 (see http://www.freedesktop.org/wiki/Software/PulseAudio/Notes/2.0/) gave me a syslog-error, stating webrtc is an unknown canceller impementation. When looking at the pulseaudio package-dependencies I can't find libwebrtc-audio-processing-0 opposed to debians pulseaudio-package (see http://packages.debian.org/de/sid/pulseaudio). This leads me to the conclusion that it's a package-build-failure.
