Thanks for the reply. That was exactly my thought process too. I've tried 2 headsets that worked perfectly fine with the other computers I have at my house. I really have no idea why that is. I don't hear it (unless I enable the Listen to this Device Option), but it drives anybody in a skype call with me crazy
The jack doubles as a line-in jack and in the properties it stated "If you connect a microphone, you may hear feedback." What the... As far as I can tell, there are no other jacks that is solely a mic-in. Whenever I plug in anything analog, it will prompt me for which device I want to connect (Checkboxes Line-in or Mic-in, and naturally I select Mic-in)
To better describe the sounds, they are somewhat whirring and high pitched squeaks.
