Dell laptop line input problems

My Dell Laptop Inspirion 15 3520 does not have an option for sound input of “Stereo mix” or “Line input” in Control - Sound, only “mic” built into my computer. I’d like to record online podcasts but can’t get by Dell laptop to recognize sound coming from online, so Audacity has no sound input when I try to record something from online.

WASAPI works for me …
