ONU problem

[Panchos]

I'm using the ONU audio controller to play Ogg music in my game.

When a sound effect plays, like the player jumps, for no reason the music drops a bit in volume. There's no event that's doing this, anyone know what's going on?

EDIT: On testing it seems to fade in after a sound effect. Like it'll be playing, I jump, the volume off the music goes down to 20%ish then fades back to normal.

Could it be something to do with sound compression?

I don't know about the ONU but the built in sound engine supports OGG.
So maybe you could switch to that?
