USB Microphone is not working on Audacity

I have had no problem previously on this. I specify the setting and when I go into record, nothing is recording. Here is a screenshot of what is going on. Thank you!

Which USB microphone? Pretend I want to buy one.

Are you going through a USB hub or adapter?

See on the right Audacity is trying to send sound back to the USB microphone. You should choose your playback sound system.
