Constant Ringing

After using cheat engine a bit, whenever I enter into a game and I walk around, I get this constant ringing every time I move side to side, but never forward. I think it happens when I turn my camera too. Could this be some way of the game detecting something's been tampered with?

I am using the current EAC so that's not the problem.

Tried validating game files?

Yes I have. This didn't fix it. I'll try reinstalling it next when I get home today.
