Once again, I experienced Skype microphone issues!!! Its getting really annoying, since almost randomly I get issues. Skype is a terrible program and depending on a proprietary thing like Skype is a real pain in the ass.
This time it was totally strange as there was no way to record any voice inside Skype Call while testing with (Echo / Sound Test Service)
After a lot of puzzling and getting a bit angry I found this time the issues are caused by some settings which somehow changed in GNOME Sound Preferences microphone to mute:
You see on above screeshot that somehow the stupid thing get mutted 😐
After unmuting and restarting Skype, the microphone started working in Skype again …
