I recently bought something similar called an M-Audio USB Audiophile DAC. I
had to turn my computer off, connect the device to the USB output. Then boot the computer back up. Then I had to go to preferences -- sound -- output -- and select the M-Audio device so the music would play through the USB instead of the headphone jack or the internal speakers. Then, I had to go to the general preferences and click on the device's logo and select the output I wanted, which was ANALOGUE OUT and "24 Bit." I clicked the checks OUT of all other boxes. Then RESTART the computer. Try that.
