I am playing both background music and gameplay sound in my game. But, while playing, the 2 sounds are overlapping and thus giving a bad effect. How can I solve it

i created two objects with audio , radio and sfx. One plays music, the other sfx. Added audio and dropped in editor variables instead of resources.
I instantiate them in my players start().
This also means that i can access those objects from anywhere too set music, sounds etc.
