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:
- How To Enable Echo / Noise Cancellation Of Microphone Input On Your Linux Desktop (PulseAudio)
- Disable volume auto adjust in pulseaudio “module-echo-cancel”
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:
Enable the pulse echo/noise reduction module so that it is always on by default (also after reboots).
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.
