Game volume

Any way to decrease game volume? The microphone I brought doesn’t work. Bunch of thieves! Anyways, I have to use my computer headphones to pick up the voice but the game volume on Reach can be VERY loud and I can hardly hear what they are saying.
So any way to fix this?

I already know the answer to this

Turn down TV, turn up microphone?

Uh, I can only hear trough the TV. I have the headphones connected to the TV to be able to hear voice. I have my microphone connected to my controller to be able to transmit voice.

I have to turn the volume way down when I go onto any other game…

Go into preferences via the xbox guide and take it from there.
