How to enable microphone echo cancellation in openSUSE? I found manual for Ubuntu https://askubuntu.com/questions/18958/realtime-noise-removal-with-pulseaudio , but it looks there is no such module in openSUSE 42.3.
I’ve never used it, but the module is valid (since PA version1.0). I just checked with
pacmd load-module module-echo-cancel
Add the necessary entry to /etc/pulse/default.pa with your favourite editor (as root).
