The I2S interface commonly supports up to 384K PCM rate from I2S drivers but the Merus chip IIRC is hardware limited to 96K. If you are doing 192K into the USB/I2S board then what rate is being sent to the Merus chip?
I'm not sure whether there is a Linux configuration that would allow both I2S and USB audio interfaces to be active at the same time. Typically when an I2S overlay is specified in /boot/config.txt ALSA configures it to card0 and no other cards are available for other audio devices.
You might want to consider using a Kali reclocker but like everything else that uses trailing edge chips its on back order at suppliers.
