My mic doesn't work on Skype for Linux (8.73.0.92) on Ubuntu 20.04.02, but it works with all other apps, including Zoom and Audacity. Skype also works on the same laptop when I run Windows.
I tried these two:
https://wiki.archlinux.org/title/PulseAudio/Troubleshooting#No_microphone_on_Steam_or_Skype_with_enable-remixing_=_no
https://wiki.archlinux.org/title/PulseAudio/Troubleshooting#No_microphone_on_ThinkPad_T400/T500/T420
None worked.
Here is the output for pacmd list-sources, in case it helps.
