This was not happening on my old computer with the same headset. For example when I'm playing any game or listening to music and talking to someone, they can hear everything that is happening with crystal clearness.
The problem I am having is this: when talking to someone in Skype, my microphone is somehow picking up any output audio that my headset is receiving. Not using a sound card either, just using an integrated one. The one I have now is Windows 7 64 bit home premium.
I just recently bought a new computer and I did not have the same issue on the old computer (which was XP). I have a problem that I hope can be fixed.
