DCS vivaldi upsampler only play low resolution music trought the streaming

Problems playing 24-bit high-definition audio via upsampler. I have the complete Vivaldi Apex DSC with clock and the Mutec Ref 10.
When playing files via mosaic or even low-resolution USB, 

Even with the clock disabled, using the internal clock the problem is the same.

I have 1 Melco s100 and a Sotm with linear font instaled

The information that you provide is a bit too sparse to enable us to suggest what is going on. So perhaps you will kindly give some further details.

Exactly what are your problems?

What streaming service are you using?

How is the Vivaldi upsampler configured? Are you upsampling to a higher resolution or are you trying to play native high-res files from the streaming service?

How is the upsampler connected to the Vivaldi DAC?

I am unsure what yu mean . To play files requires playing software, you cannot play by USB on its own. Do you mean using the Melco playing app connected by USB? Is USB 2 selected ?

Perhaps you could explain. I have no idea what the SOTM device is ( they make several) nor what a linear font is.

I have no guarantees that I may have an answer to suggest but this additional information will allow me to think further.
