Click Issue - Audio-GD NFB-28.38 Over USB

I’ve had my Audio-GD NFB-28.38 for a few years now. I have always used it over USB from a PC.

It has always had an issue that sounds/music through the unit are interrupted by clicks every now and then, whether it’s used as HPamp or Preamp. The clicks come through the HP’s or Speakers themselves.

The unit uses Amanero USB interface. Does anyone know how to fix this issue?

Have you tried completely to reinstall the Amanero drivers? Or possibly try it with another PC or try it with the optical cable if your PC supports it (the connection with the red led )
