This is my best hunch for dealing with the issue, but I don't quite know how to go about correcting this. of not any or it doesn't work, you need to go to the audio supplier's site and look for one. Go to the driver page on the Dell site and look for a Win 8 driver.

On the Confirm Device Removal dialog box: Click the Delete the driver software for this device option to delete the generic Windows driver. Right-click RealTek High Definition Audio, and click Uninstall. Expand the Sound, video and game controllers node in Device Manager. The two listed options are '1-digital display audio' and 2 'speakers/headphones'. Most likely, Win 10 installed a Microsoft generic driver. Right-click the Windows Start button and choose Device Manager. The other suggestion was to make sure my headphones are my default option. The drivers within this category all are updated already. The two primary ones I saw being update your sound drivers which if I navigate to my device manager, I only see one category related to sound called 'sound video and game controllers'. I have already searched online and found various suggestions to fix this. I doubt its an issue with my headphone jack because I'm incredibly careful with it when I plug in and remove my headphone cords. It's not an issue with the headphones because I have tried them on other computers and I have tried other headphones on my laptop. With my relatively new laptop, my headphone jack was working just fine up until a few days ago when all of the sudden for as far as I can tell, my headphone jack stopped working.
