After getting on my PC (windows 7) this afternoon, I noticed my headset made what sounded like a clicking sound in just the left ear, and didn't provide any other audio at all, nor did the mic on it work. I tried different cords, but to no avail. When I go to playback devices and recording devices, my microphone and speakers say they aren't plugged in, but occasionally flash saying they are - however only for a split second. Any help appreciated!
