XPS 13 Plus 9320, sound not working

I just got my new XPS 13 Plus laptop in the mail a couple days ago. Everything was great on the computer until I ran into a sound problem. I connected my bluetooth headphones to the computer. No problems occurred when connecting and listening with my headphones. The problem is when I disconnected the headphones and now I do not have any sound. I would consider my self as a pretty tech savy person, so I went through the process of troubleshooting and could not find a solution. I read some other forums on the Dell website with the same issue but not solution.
