Assuming you have Video Easy and the Magix USB Video Capture dongle, the camera should have a composite audio output which you use to connect the DV camera, with the Composite cable you should have with the camera - these usually have mini jack plug with 3 rings and tip connection and yellow, red and white plugs on the other end, to the dongle and computer as shown in the manual avaialble under Help in the program.
In Windows 11 Settings, Privacy & security, Camera and Microphone options you have the Let desktop apps access your camera/microphone options are enabled - you may have to scroll down the Camera, Microphone options to see this.
Note you will have to start/stop the camera playback manually.
