Could you please take a look at the attached screenshot?

I'm encountering an issue where my 'line in' audio isn't appearing as an available audio source while recording the screen with Vegas Capture.

It only displays the speakers (output), not the input. I've ensured that 'line in' is set as the recording input both in Windows (10) and within Vegas preference itself. However, it still doesn't appear in the VEGAS Capture window.
