Do you mean the sound turns off when a cd is inserted into the deck? are you running your audio through and amplifier? if you are using an amplifier, you are probably using the blue wire (antenna remote turn on) instead of the blue/white wire (amplifier remoter turn on) to turn the amplifier on. the blue wire turns off when you are not in tuner mode.
