Crackling and buzzing sound on videoconference

[JaimeCS]

Hi everyone! I'm experiencing some crackling and buzzing sound on videoconference, like Zoom and Teams. The other participants hear me well, but in my notebook, there is some crackling and buzzing sound, especially over volume 50.

I've tried with all the updates.  

This does not happen when listening to Spotify on watching movies on Netflix, or when I'm with headphones.

Anyone has experienced the same or knows how to fix it?

Thanks a lot.

I'm having the same problem.  However, it only happens to me when I have my HP Pavilion - 15-cs3153cl notebook power cord plugged in.  If I'm running on just the battery, the sound is good on Zoom or other Video Teleconferencing services, but not when I have the power cord plugged in.

I've tried plugging it in a separate socket with nothing on the circuit, but still the same problem.  Also, it seems to happen with 4 or more people on Zoom.

Did anyone respond to you separately about a fix?

Does anyone have a fix for this?

Thanks

Thanks, C_Tommy. Unfortunately, it also happens when not plugged in. It even occurs when playing YouTube videos that have audio recorded from a videoconference. When using headphones, it disappears or it is very low.
