Can you clarify that? Pushing in the clutch pedal is disengaging the clutch. Releasing the clutch pedal is engaging the clutch.
If it gets quiet when you push in the clutch pedal, I would suspect the throwout bearing.
Another thing I noticed on the way home today is that the little speed limit reminder in the gauge cluster says kilometres even when the units are set to miles. So that is following the speedometer. @Ford Motor Company really needs to figure this out.
