Nope, hooked up my back up DAC and all was well. The first one I sent back was sent back to me as repaired with a note saying audio board replaced, still did not work. Sent it back again requesting a new replacement which they did. Lasted a month.
Disappointed is all as liked the darn thing and the sound for a middle road DAC.
It usually takes 2 marginal devices for an issue to surface. I would not discard a possibility of a faulty USB port on your PC.
