Ubuntu 18.04 Microphone crackling / popping sound

Solution 1:

I found this solution Video , and it worked for me.

Open Terminal and run:

sudo nano /etc/pulse/default.pa

Add these lines at the end of the file:

### Enable Echo/Noise-Cancelation
load-module module-echo-cancel aec_method=webrtc aec_args="analog_gain_control=0 digital_gain_control=1" source_name=echoCancel_source sink_name=echoCancel_sink
set-default-source echoCancel_source
set-default-sink echoCancel_sink

exit from text editor with ctrl+x and save file.

run

 pulseaudio -k
 pulseaudio --start

restart the system.

Done!
