with firmware V1.01.084, when connect the DX160 to my computer (win10 64bit & win7 64bit) as usb dac,not every usb port can recognized DX160, even can recognize DX160 as usb dac, there will be some clicking/hissing noise when playing music, had try using another cable but still can't solve the problem, this will not happen when connect to my android phone as usb dac, only happen when connect to computer, is this a firmware problem or hardware problem?
