No audio Split Fiction

I am not sure what happened but I played the game and heard it just fine. Then all of a sudden I heard no audio. When I played with my boyfriend I had the issue but I somehow fixed it. This time, I am playing with my brother and I cannot for the life of me figure out what is wrong. It's not my pc since I can hear the other games I played but I do not understand how my brother can play with audio and mine does not work.
