Razer opus discod problem

When I use Discord, there is no sound of the game but the voice of the friend is not heard or vice versa. In online games, I need to hear both the sound of the game and the voice of the friend. This is a must for the player. How can you fix this problem If there is a bluetooth problem, suggest me a bluetooh that I can buy. Why does the headset not have a bluetooth device of its own.
