HP Pavilion 11 x360 Headphones Problem

Ever since I took the back of my computer off to fix a hard drive issue, my audio jack hasn't been working. I tried using both sets of headphones, and usually my computer has the Beats Audio thing that pops up and says that I've plugged a device into the audio jack. It doesn't do that anymore, and all there is is sound coming from my computer speakers, and not from my headphones. Is there anyway to fix this, or is my audio jack broken?
