If I run "pacmd load-module module-echo-cancel channels=2" The loading fails, pulseaudio crashes and restarts, and I get this in syslog: "Mar 9 16:13:26 trancendence pulseaudio[2303]: [pulseaudio] speex.c: AGC, denoising and echo suppression only work with channels=1" Not sure if the webrtc engine supports more than a single channel, it fails to load on 12.10: "Mar 9 16:08:44 trancendence pulseaudio[2303]: [pulseaudio] module.c: Failed to load module "module-echo-cancel" (argument: "aec_method=webrtc"): initialization failed."
