It seems baresip has an EC built inside, as Russell said in a previous comment. If it doesn't work correctly, i will try your updated version of webrtc.

I'm seeing these kinds of errors constantly with module-echo-cancel (also running on ARM): module-echo-cancel.c: Doing resync module-echo-cancel.c: Playback too far ahead (22312), drop source 2 852 module-echo-cancel.c: Doing resync module-echo-cancel.c: Playback after capture (-1309936), drop sink 167708 I don't know what their cause is, but for me they don't seem to be causing any noticeable audio quality problems. I do find the current state of echo cancellation in Pulseaudio unusable, but that seems to be due to the echo cancellation algorithm not working properly for my use case. It might be the same for you. I've made an updated libwebrtc-audio-processing and a patched module-echo-cancel that works significantly better for me. I've sent it out to this list three months ago without much response. You might want to try it if it helps with your problems. You can get the code here (both should build with "dpkg-buildpackage" on debian-like systems): <a href="https://github.com/avian2/webrtc-audio-processing/tree/debian">https://github.com/avian2/webrtc-audio-processing/tree/debian</a> <a href="https://github.com/avian2/pulseaudio/tree/debian">https://github.com/avian2/pulseaudio/tree/debian</a> Best regards Tomaž _______________________________________________ pulseaudio-discuss mailing list pulseaudio-discuss@lists.freedesktop.org <a href="https://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss">https://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss</a> </div> </div> </body> </html>
