Xbox 360 Sound issues

So I just bought my 360 on friday, been playing dead rising non stop. But for some reason anytime it does a cut scene, there is no sound!

Sound works fine while playing the game, and during other games, demos, videos and the arcade.

Just not during the cut scenes. Anyone know what my problem is, and how to fix it?

I don’t know much about it, but post back what cords you are using, what TV, etc. So there is more to go on.

Using the standard cords that came with it.

But never mind…turns out the problem was I had turned the BGM volume all the way down for some reason and that counts as Cut scenes as well…

I am fucking retarded

Might be the disc best thing to do is to get a new one from where you bought it.
