Can't hear Audio with Aux 3.5mm audio cable

AC Question

Have been using my Samsung Galaxy Avant for 9 months to listen to podcasts and audio books on my drive to work. My cable started to crackle and died. I have bought several new cables and i can not get the audio to be heard. I have also tried to used the cables on my laptop but could not hear it. Phone registers that the cable is plugged in, so did my lattop yet i heard nothing. What i really don't get is that head phones work fine.

Help please!
