Hey what’s up Tzion? Glad to see I’m not the only one who’s gone through KDE-Audo Hell
Have you tried opening up the Audio settings (usually either the icon down in the task manager or Settings → System Settings → Audo in the main menu)? If you go to the Advanced tab you might see the microphone listed there, and you’ll be able to turn it on using the dropdown menu. As well as turn off any built-in microphones your system is defaulting to. After over a year of remote working on Parrot as my daily the only thing that is still a pain in the ass is Pulse Audio haha.
Let me know if that helps at all and if not we can try some deeper debugging.
