I'm trying to use the echo cancellation module on my embedded platform but it seems to be taking all the cpu usage and renders audio useless. I'm continually seeing these messages: warning: The echo canceller started acting funny and got slapped (reset). It swears it will behave now. D: module-echo-cancel.c: diff -269 (43555 - 88163 + 44155) 0 0 9600 184 E: module-echo-cancel.c: Playback after capture (-269), drop sink 84 warning: The echo canceller started acting funny and got slapped (reset).

I was loading the module like so in my .pa conf file: load-module module-echo-cancel source_name=echosource source_master=pcm_input sink_name=echosink sink_master=pcm_output rate=44100 channels=2 Is there a step I am missing, or a link to documentation on how to set up the module properly?
