Python-vlc, RasberryPi and looping script MP3 only plays one time

[musiceverywhere]

The following is for a Gate Annunciator. IR Beam creates a contact closure, and MP3 file plays. However it only plays the first contact closure. After that the code runs a it should but no sound.... I'm lost any help is greatly appriciated!

Code: Select all
