Very light buzzing noise in headset when my laptop uses microphone

Any buzzing in an audio device is usually caused by a dodgy earth, either in the device, the cable, or the connector. Earth failure means the audio channel is not properly screened, which means non-signal noise is picked up by the device.

To help discover which it is, follow the instructions given by SpywareDr.
