Yea I had to format my PC and re-install windows 7. When I originally had it installed I went to playback devices and picked set as default to get it to work. After the re-install, the headphone device always said headphones not plugged in (though they were.) I since browsed the internet, went to Realtek and installed the drivers
. Now, the headphones don't show up at all. How can I fix this?
