What operating system are you using? And, are you using stock Windows drivers (like those that come with the Windows 7 Install DVD) or did you download directly from the vendors? What make/model of motherboard (and sound card if not using on the on-board sound) are you using?

can you re-assign the audio jacks, as a mic and speaker electrically are very similar.
