How to make sound run continously in the background of my experiment? (i need to use randomization in loops)

Description of the problem:
Hi, I am new to psychopy and a beginner in coding, I am trying to build an experiment for multimodal perception where i am checking for the perception of certain kind of illusion images when there is a continuous background audio (with the current builder, new audio is getting played every time the trial ends). Hence how to achieve this continuous audio stimuli in the background.
Note: I need to randomize the order of the images hence can’t use cut pieces of the audio file and use sequential in the loop.
