I am new to linux and want to use it as my daily driver however, I want noise cancellation for my mic and after some googling, I found out that you can edit the pulseaudio config file to load the specific module for it as shown in this :-
https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Enable_Echo/Noise-Cancellation
So I opened terminal, typed
sudo nano /etc/pulse/default.pa
and then added the lines
### Enable Echo/Noise-Cancellation
load-module module-echo-cancel use_master_format=1 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
after that, I rebooted my computer but everytime I did something related to voice recording made my computer freeze for about a second (like going to Settings->Sound, starting a voice recording in Counter Strike Global Offensive, testing microphone in steam etc…).
Then I opened pavucontrol
and saw this :-
Does anyone have a clue as to what I am doing wrong?
Running sudo journalctl -xe | tail -25
gives the following result :-

I found the solution to it, before editing the config file, I had to make sure that the hardware for built-in Audio was configured with the profile "Analog Stereo Duplex", I had it on "Analog Stereo Output" as pointed out by :-
