Hello fellow Wolf

Welcome to PCHF.

- Can you go to My Computer, Control Panel, Sounds and Audio Devices.
- Click on the Audio tab.
- Under the section "Sound Recording", click Volume.

The problem you may be having, is that "Stereo Mix" or "Audio Mix" is selected at the bottom. Put a tick in "Microphone" instead and see if the noise goes away?

if i tick microphone the mic dsnt work at all.... i hav to tick rear mic to make it work...the headfone jack is in the green socket and the mic jack is in the pink socket

The colours don't always match, but how does it sound with rear mic ticked by itself? If not, can you tell me the name of the default device in Sound and Audio Properties?
