Recording Won't Work

Audacity 2.3.2, Windows 10.

Hello everyone, newbie alert! :wink:

:slight_smile: In the past, I have made several recordings using Audacity to record soundbites from videos that are playing through my PC from websites.

:astonished: Now, it suddenly no longer works for me. I press the record button, but nothing gets recorded.

:confused: So, Iā€™m sure Audacity is not at fault, but something most likely needs tweaking on my PC.

:unamused: Any ideas?
