Hi,

I am not sure what your question is here. Can you be more specific about your setup and desired configuration? Can you please attach your SigmaStudio project? Thanks.

Regards,

Hello,

Please check the datasheet's "S/PDIF Receiver and Transmitter" section. You can find it on page 65.

The highlighted sentence reads:

The S/PDIF ports work with sampling rates between 32 kHz and 108 kHz.

In other words, they will not work at 192 kHz.

Thank you,

Brett
