Hello, @alex.gilgenbach. Please, try installing the Focusrite Control Driver with your audio interface unplugged.
If the installation finishes normally, restart your system and plug your audio interface. Then make sure you have the correct device enabled on your system sounds (Start > Type “Control panel” and click it > Hardware and Sound > Sound). Your audio device should be enabled with a green checkmark on the “Playback” and “Recording” tabs. Make sure you have only one audio device running at a time.
