arduino waveshield - servo motor problem

hi everyone

i need help im making my project with servo motors and waveshield. im having problem with waveshield when the servo motor is attach to arduino.. the sound is not working..

but when i remove the servo motors to my circuit the sounds work. i have 2 supply, one for servo motors and 1 for the whole circuit..

i used gizduino x arduino
http://www.e-gizmo.com/KIT/gizDuino%20X.html

and wave shield from ebay.
