Thanks for the info. So a major takeaway here is that I can’t use Vegas Pro for this. The capturing device I have does make a sound when I plug it in. And it did come with a small installation disc which I can’t use on my PC. But the instructions said I could download/install OBS which I did. It then says to open “applications – QuickTime Player”. Then “File – New Movie Recording”. Then select “AV TO USB2.0”. However I’m not seeing these options on QuickTime Player when I open that.
