Servo with audio shield attached

[terribleidea]

are there any issues with regards to controlling a servo, even with an audio shield attached?..

I was trying the code found here : https://www.pjrc.com/teensy/td_libs_Servo.html

and the servo doesnt seem to move or anything..

I am planning to use the servo together with the audio shield attached. since i want to control the servo based on the specific FFT bin/point amplitude..

servo teeensy

GND - ------- - GND
SIGNAL/ DATA - -- pin 29
VCC - ------------ -5v external power..

currently having this code for the mean time to test the servo only ...
