stop() method on
AudioScheduledSourceNode schedules a sound to cease playback at the specified time. If no time is specified, then the sound stops playing immediately.
Each time you call
stop() on the same node, the specified time replaces any previously-scheduled stop time that hasn't occurred yet. If the node has already stopped, this method has no effect.
Note: If a scheduled stop time occurs before the node's scheduled start time, the node never starts to play.
