Good evening Gentlemen,
I received another DAC from the manufacturer and that one also had the clicking through USB. I purchased a $50 converter on Amazon that takes usb to I2S and now THE CLICKING IS GONE!! I2S has solved my dilemma and pretty cheap as well.
I don't know what the USB problem was and don't think I will ever figure it out but I wanted to thank you all for your great ideas and brainstorming.
Kind Regards,
Joe
