So I drive a 2015 Mazda 3 6MT. I originally had the whining noise as well but I found out the cause for mine. When my radio was set to AUX, and a device wasn't connect to to wire, I'd get the wine. But when a device was plugged in, it would stop. So I ask a friend who is a mechanic, he claimed the Wining sound was caused from feed back by the vehicle itself. So to test to see if this was true, I unplugged the cord and got zero wine. I plugged the cord in with no device connected. I had the wining. Finally, I connected a device and testing one more time. No wining. So I believe the statement is true that the wining sound is caused by the feedback from the car itself.
