The USB port is recognized by the computer and JRiver but no music. When I switch to SPDIF input no problem TP1_SMx.jpg (192kb) downloaded 26 time(s). TP2_smx.jpg (203kb) downloaded 28 time(s).

I suppose the usb board is suspicious and will get another one

I now get lock lite but low volume and distorted sound. It doe not matter whether I use ANSIO or WASBI drivers for XMOS usb board
