My laptop microphone pics up a lot of whiney and white noise which is intolerable for my coworkers to listen to.

I have tried to follow a myriad of guides on how to enable the pulse echo/noise reduction module, like these ones:

However, settings don't persist after a reboot: when going into the "sound" menu, I can only choose my microphone input device without any noise reduction.

To make things worse, when the echo/noise cancellation module finally is loaded (just after having edited /etc/pulse/default.pa), the automatic gain adjustment goes nuts by turning the microphone gain up and down like a roller coaster.

In short, I (and all of my windows co-workers) would really, really, really appreciate if someone can provide me with an easy to follow guide on:

  1. Enable the pulse echo/noise reduction module so that it is always on by default (also after reboots).

  2. Persistently disable the automatic microphone gain, so that microphone gain can only happen if I manually adjusted through the sound settings.

My laptop is an MSI GS66 running Ubuntu 20.04.1.

  • Thank you for your comment. Unfortunately, this doesn't seem to work for me; the input volume/gain still goes up and down (mainly up) uncontrollably. Can I ask, do you do "pulseaudio -k && pulseaudio --start" after every reboot in order to be able to enable noise cancellation? – Nils Sørensen Nov 05 '20 at 16:19
