It's not letting me record now (10 years later)

I used to use this program 10 years ago. I would love to get it on here working, but I keep getting the following error when pressing the record button. Any help would be appreciated.


What are you recording?


I got it to work. A trick I learned a while back when using the mic was to disable everything but the mic in the sound recording area through the control panel. In this case, I was trying to record just audio through the computer. So, I did the same and disabled everything but Stereo Mix (which was already checked). I wonder if there is a way Audacity can auto check it and disable, then revert back when done instead of constantly going into the control panel.
