ADC6140EVM-PDK: How to get true 8 channel 768kHz hardware sampling rather than software resampling on Windows and Linux?

Part Number: ADC6140EVM-PDK

It seems both Windows (192kHz max?) and Linux (ALSA: 384kHz) have maximum hardware audio capture sampling rates below 768kHz.

When a sound recording application like Audacity is asked to capture at 768kHz, it uses software upsampling to do so. I would like to get

actual 768kHz sampling rates from the ADC6140EVM-PDK in both Windows and Linux.

1) What software (open source or commercial) is recommended to do this?

Audacity can be set to sample at 768kHz, but on Windows it is not clear what the hardware sampling rate actually is. On Linux, it seems to be 48kHz,

with the difference made up by software upsampling.

Commercial software Sound Forge Pro 16 https://www.magix.com/us/music-editing/sound-forge/sound-forge-pro/

and Reaper https://www.reaper.fm/ seem to have 768kHz sampling rates, but I expect the same resampling issue to arise.

2) How can I confirm that I am actually getting the requested 768kHz sampling rate from the ADC6140EVM-PDK?

On linux one can look at /proc/asound/card1/pcm0c/sub0/hw_params during recording.

Is there a comparable check in Windows?

Thanks,

Chris
