Audio playing through headphones and speakers

I have my headphones plugged in and the audio is playing music through the speakers and through the head phones. Originally there was a message by Dell Audio telling me "You just plugged a device into the audio jack" then a millisecond later "You just unplugged a device from the audio jack". I have my headphones plugged in but those messages keep popping up.

I deleted and reinstalled Realtek and this is still happening. I pushed the headphones into the audio jack real hard and it stayed at "You just plugged a device into the audio jack" for a little while then it went back to "You just unplugged a device from the audio jack". This is driving me crazy. I just want to listen to music through my headphones

I have a Dell Inspiron
