There is a switch on the clutch pedal that will disengage the cruise control when pressed in (similar to the brake pedal).

The engine will sound different when the clutch is in or out. When the clutch pedal is pushed in, the transmission is not spinning at all because there is no mechanical link to the engine. With the clutch out (and the trans is in neutral) there are still some components within the transmission (and clutch) that are spinning, even though the car is not moving. This does create a slight drag on the engine, so I think that this is the difference you are hearing. Again, as everyone has been saying, this is NORMAL.
