What would cause but a whining noise when the clutch is pushed to change gears

What is your question?

When I push the clutch in, I makes a whining noise. It stops when it's released. Gears shift fine.

What makes this problem better or worse?

Don't know haven't driven the car. It's been parked since the problem began.

How long has your 2000 Subaru Outback had this problem?
