Douk U2 pro with upgraded clocks - need explanation

Received today my leaf cmd-17 with upgraded clocks, and my dac just show me : no signal message.
I tried to change hdmi cable, tried to install driver from manual, device is detected by windows, but dac shows - no signal:(

What should i do, to make it work?:frowning:
@Pokrog please assist

Coaxial connection works, but the sound quality is weak, direct connetction to D1se - usb sounds much better then this converter board. At the moment - this purchase, a big disappointment :frowning: Because from the exit i2s for which I bought it - there is no signal.
Trying to find how to make i2s - work
