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
