ok. but is there is no a similar function to stop vibration. In fact as far as i know vibration feedback does only one vibration at a given time, I have created 12 distinct vibration patterns with varying intensity and no of vibration and duration. These vibration are associated to each Ui.Button and Keypad used as hotkeys. Idea was to put them in separate threads and kill the thread whenever required.

In the meantime i will try to dump Sound thread and use as u suggested QSound::stop() and see how it goes.
