It's all just a big guess unless we know exactly when the whine starts and stops.
Just as the clutch is starting to contact the flywheel, or before?
Just as the trans starts to turn and the car is starting to move?
Does it do it when cold with the clutch already pressed while you start it?
Does it do when when cold and you sart it in gear with the clutch in?
How about right after you start it, then shut it off and restart does it do it again?
See what I mean?
It can be narrowed quite a bit knowing these answers.
