Background Music Masks Sound Effects

I have background music and sound effects for jump etc. In Editor, I adjusted the volumes and everything is fine but when I build the game I can’t hear the sound effects because of the background music. It masks all other sound effects which is a huge problem. Why there are differences between build and editor versions? Can anyone help me?

I solved the problem. Maximum volume of the audio files I am using was incredible low. By using a software I increased the maximum volume so problem solved in Unity.
