Why is there no music in Left 4 Dead 2 and how can I make it so that I can hear it

well is your tv the really old ones where there is only 2 conections yellow (video) and white (audio) well if so then the red (which is the rest of the audio ur missing ) isn't plugged in and that's y there isn't music so either get a newer tv with all three analog plugins or component or get a hdmi cable and a tv with an hdmi input
