Your device is set to 'DAC Mode' which fixes the output at maximum level (0dB) to feed a dedicated amplifier. To adjust volume on the device itself, enter the Setup Menu and change the mode to 'Pre-amp' or 'PRE' mode.
First, check that the correct input (USB, OPT, COAX, BT) is selected on the display. Ensure your computer sound output is set to the TOPPING device. If using USB on Windows, ensure the correct driver is installed. Finally, check cable connections to your amplifier or speakers.
