Whenever I my headphones get unplugged and then plugged back in, the sound in some of my applications stops working and I have to restart them to get the sound back. Sometimes the sound devices thing stops working and freezes and I have to restart my laptop to get sound. And I think it also happens if I start my computer without the headphones plugged in and I try to plug them in after. How do I fix this?

Which applications? Is it always the same one? What operating system are you using?

Windows 7. StarCraft 2 and Heroes of Newerth are the ones I notice. I think it happens with Firefox too. Winamp usually works without having to restart it, however it also sometimes freezes when my whole sound devices thing gets messed up. When I try the troubleshooter thing it says there's nothing plugged in, even though it is.

It is likely that the headphones jack is set up as a different sound device. I'm not sure whether there is a way to change it without installing additional software, but there might be.
