faild to record from PC

I have windows 10 and Audacity 3.1.3. When I try to record from youtube I click on the record record button the time line does not move. I tried to reinstall Audacity but it still does not start. It used to work but I haven’t used it for a while. What am I doing wrong?

WASAPI loopback recording does not start until after the audio source starts.

I don’t know why my audio from youtube is not getting to Audacity program

See: Tutorial - Recording Computer Playback on Windows

And, make sure to select the loopback device where the sound is coming out… Usually that’s your regular soundcard/speakers but if you have a USB headset (or something like that) plugged-in, you might get the wrong thing.
