Slow playback from ipod
 

I'm new to owning a Mazda (2018 3 touring sedan), and I'm looking for some advice.
I'm having problems with USB connectivity for my 160gb ipod classic.
I don't have any problems connecting the ipod, but occasionally it will play the songs at like 2/3rd speed.
No idea why it happens or how to fix it. Everything works fine with an aux cord, but I have the ability for a USB connection so I'd like to use it.

Anybody have any recommendations?
