Car2PC-MAZ adapter usb engine noise
Not sure if I'm posting this the right spot but here goes.
I'm having an issue with slight engine whine with my Car2PC-MAZ adapter. If I disconnect the USB cable coming from the Car2PC-MAZ adapter and use it solely as an aux sound input using the 3.5mm connection the engine while will disappear.
I'm using a Carnetix 2140 and P5v (sits inside the 2140) psu, the engine whine will only occur when the USB cable is connected coming from the Car2PC adapter either to the hub or directly to the PC.
Note I am using after market amplifiers and speaker none of the other inputs have an issue with engine whine I.E CD, radio etc.
Any input would be greatly appreciated.
