Recording Confusion

I have been using this software to record my songs for a long time, and usually it records through my headphones. Now, it’s just recording through my computer mic, and it’s not playing through my headphones. All other sounds play through my headphones, but audacity recordings don’t. Also, on other software such as Skype, I can speak through my headphone mic. I don’t believe that this is a problem with my headphones, so I would like some help, thanks!

If you go to Audacity preferences , devices, you can choose what device Audacity records from, and plays back through.
