Noise cancellation module not working

Asked by Kalpesh on 2019-12-28

I plugged my microphone to the ubuntu and while doing Skype calls, there is continuous noise. After searching online, I tried to add the noise cancellation profile but then pulseaudio stopped working.

Here is what I tried:
sudo nano /etc/pulse/
load-module module-echo-cancel

After this, when I opened pulseaudio after reboot, it stopped working. Showing the error message as:
"connection to PulseAudio failed. Retry in 5s" but it never worked. It starts working again if I remove that line.

After some more research, I tried this command:
pactl load-module module-echo-cancel

and it shows this output:
Failure: Module initialization failed
