Problem: Lots of background noise on the internal microphone. If I record it in Audacity it seems that most of the noise is in the Left-Front channel. The Right-Front channel is still noisy/bad quality, but not as bad.
Hardware: Dell XPS 15 7590 laptop (basically 2019 model)
OS: Ubuntu 20.04 fresh/plain installation:
$ lsb_release -rd
Description: Ubuntu 20.04.1 LTS
Release: 20.04
Other tests:
- If I use a external/USB headsets+microphone sound is fine
- If I boot from Ubuntu 20.04 live USB it still has the problem
- If I boot from Ubuntu 19.10 live USB it still has the problem
- I tried many steps involving changing config files e.g. https://wiki.ubuntu.com/Audio/PositionReporting + reboot, none fixed the problem, reverted the config files back after every change
