I would guess it's the throwout bearing. AFAIK, it's not something to worry about, just noise, not something horrible about to happen. I could be wrong, but with you saying it stops when the clutch is in, that's what it sounds like to me. When you have your clutch replaced, that is normally replaced as well. Just have it done then.
