I purchased a D4 several months ago and have been using it as a DAC on my Macbook pro17 inch. It has worked great ever since I got it. Just this past week though, I noticed that the DAC would stop working and would no longer show up on the audio list on my computer. I checked my D4 and noticed that the usb cable was a little loose in the usb port of the D4. But the cable has always been able to wiggle a slight bit. I tried wiggling the cable and did notice that the DAC would show up for a quick second on the computer. Now it no longer will show up. The blue light and red light still light up on the DAC, but the DAC will not work. I know the problem is not with the computer since I have checked the usb ports on the computer with multiple devices and they all have worked except for the D4. The D4 is in pristine condition and I don't understand why this would happen. If anyone could help, I would greatly appreciate it.
