Cubox i4pro with Toslink and DAC

Hello!
I have recently installed the latest version of Volumio (volumio-2.857-2020-12-16-cuboxi.img.zip) for my Cubox i4pro, now I have connected the toslink to a DAC Techole HS202 (https://www.amazon.it/gp/product/B07MB8VCWQ/); after the changing of output device with “Integrated SPDIF” I have not signal to the mixer.

I have also tried to check the signal directly form the DAC and unlucky there is just a little noise.

Any suggestion to solve the problem?

Thanks in advance for your help!
G.
