Microphone not working

The Microphone is not working, at least in my fedora Workstation installation. The gnome shell menu it say me for a second that mic is being used but it close the mic dialog.

Yeah. Unfortunately it doesn't work in the non-flatpak version either. It works fine if I load onlinemictest.com instead of duolingo though.

Getting the listening and speaking exercises already requires a workaround, as Duolingo blocks them by default on electron apps. Until I can find another solution (if it's possible), I am going to remove the current workaround, to avoid confusion.

This is just an idea, why you don't try make the duolingo app in WebKit (Gnome Web) instead of Electron? idk if it's possible
