My program slows down when executed several times - buffer problem?

ruski15

Apologies for my ignorance but I am trying to run this code and I feel it is less sensitive to the mouse movement when I run it several times. Please try it and let me know. It happens when you press Silence and then Sound again. The more you do it the slower it gets.

Is this a buffer problem?

Any solutions?

Thank you!
