Ubuntu microphone noise cancellation and volume auto adjusted issue

I am try to streaming my work demo via YouTube and recognized Ubuntu don’t have noise cancellation option in sound setting.

Here is the solution i found (googling)

Enable Echo/Noise-Cancelation

Arch does not load the Pulseaudio Echo-Cancelation module by default, therefore, we have to add it in /etc/pulse/default.pa. First you can test if the module is present with pacmd and entering list-modules. If you cannot find a line showing name: <module-echo-cancel> you have to add

>> sudo vim /etc/pulse/default.pa
### 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

>> pulseaudio -k
>> pulseaudio --start
