Recorder Player Problems? Ask a Technician for Answers ASAP
Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I would advise first of all that you check the USB cable - if it shows the least sign of stress to the cable, then swap out the cable.
I would think that, if the iPod plays OK without the USB connection, then the USB connection is not transmitting, and what is most likely to be at fault is the cable (or possible the jack at either end, or the circuitry in either USB port, etc.)
