My D3 is connected as follows:
Toslink (onboard)--->Optical cable--->D3--->RCAxP3 Belkin cable--->Edifier M3400, ( D3 is feed through an USBxminiUSB cable, connected to the PC)
I´m getting a hiss that seems to vary according to the port the USB cable is connected to.
Does anyone has the same issue ? If so, could you track down the cause ?
