Hi there, I have observed mysterious behavior of sound quality from live media and video conference.
Although I did fair amount of troubleshooting, I can’t figure out what could help fixing crackling noise issues. Great if you can advise what I might have missed. Many thanks.
What you expected to happen
Playback of live media and video conference work out of the box on web browsers.
What actually happened
Playback of live media (YouTube) and video conference on Google Meet running on Firefox/Chromium/Chrome web browser causes crackling noise.
