I can't see line in when recording audio

Hi there,

Apologies if this question has already been answered elsewhere but I’m new to posting here.

I have Audacity Version 2.3.3. for recording audio with a mic attached to a Focusrite 2i2 preamp. For some reason when I click ‘record’ in Audacity I can’t see the line in which means I can see or edit any recorded audio.

I uninstalled and reinstalled Audacity on my Windows 10 laptop to see if this would solve the problem but to no avail. Any solutions to this please?

Thanks,

What do you mean by “line in”?
