In a Laptop Toshiba with Ubuntu Desktop 22.04 (No Virtualbox involved) - when is pressed the print screen key is possible to either take a screenshot or record a video - it for a custom selection, the complete screen and finally for a specific window. And well, there is a red circle to start the process. It is for the default software/tool loaded by Ubuntu.
Even when is possible to record the video as .webm by default and play it with either the default tool or VLC, there is no audio, therefore the input is ignored. If is reached Settings -> Sound -> Input, I can confirm the Input Device works as expected. It by simply saying some words.
Question
How to configure this default recorder to record the voice too?
