1. Open any store item that produces audio (i.e. loading screens or portals)
  2. Quickly jump into another menu (in my case I used the inventory menu)
  3. If you hear the audio from the object in question playing in the background, then the bug worked, it will continue playing infinitely until you open any store item again.
Video attached demonstrates the bug occurring while allowing movement and navigation.
The bug does not seem to persist across world reloads.
