Volume Cracks Using Print Configurations in DraftSight/ Zooming In and Out

Started to listen to the you tube video, Using Print Configuration in DraftSight. The volume has a cracking sound and cannot listen to. Is there another you tube video available with the volume easier to listen? Also,

I noticed to the zoom command is not smooth going in and out, roll the mouse and the drawing jumps. The snap is not on. Any Ideas?

Thank You
