I think in the cvt the multi plate clutch center might be programmed to go full open mode if the e-brake is pulled to protect the drivetrain. This might be the source of the sound and could explain why it occurs with little brake application. The switch in the handle probably releases the clutch to full open if the handle is lifted at all. If you were previously moving and had some amount of locking rate between the axles, the sudden clutch release or the actuator moving might produce a sound.
