When I plug the headphones in, I can hear sound through them (albeit low quality) but I can also still hear sound coming from the computer. I can also hear a high pitched crackling sound through the headphones. This happens with any headphones or earphones that I plug in. Also, when I go into Control Panel > Sound > Manage audio devices, the headphones are not listed. Only "Speakers" are shown.
