I couldn't find any information online that helps. But, when I play GTA IV, during the cut-scenes, sometimes the voices cut out (they become silent) and what seems like the radio plays faintly in the background. Not sure why this happens. In audio options, there is only stereo and headphones. I have surround sound, but when I turn that off and make it go through the TV it still does it. Does anyone know if this is an issue within the game?
