My audio isn't working on my phone. It only works with the headphones in

I just got a new phone about a week ago. Today I was texting noticed that it was having shortages in the clicking. When I played a game the sound wasn't working. Later that day my dad called and the phone wasn't playing my ringtone. Now it will not work at all with any sounds. I have reset all my settings on my phone and turned it on and off multiply times. It doesn't seem to be working. I did try putting my headphones in and turned my music on and it was playing through the headphones but when I took them out it wouldn't play.
