Hello, I need help playing audio through my regular iPhone 5. I cannot get audio to play through my Alpine system with a lightning to USB cord. My 5s worked fine, but my 5 will just charge and not play audio. Please help, I have called Apple and they told me to ask Best Buy if they had some type of cable and they said there was no such cable. I have bought "3.5mm to USB" cables and they do not work. Is there anything I can do?
