Did you have access to documentation? I think it's a plain text file distributed alongside xConfigurator.

Resolution is set to 32bit in the xCORE-AUDIO's internal firmware.

What I meant was reducing the device to 48kHz using SAMPLE_RATE_BITMAP of the .cfg file. Then check if macOS still fails to offer a 32bit option.

Hello, I'm working with Jean-Pierre.
I understand what you mean, i found a cfg file in xConfigurator folder but how can I replace the existing internal firmware with my custom cfg file ?
You confirm it's this line ? (see Attachment).

Thanks in advance,
Jordan

The process is to run the xConfigurator script to generate a binary. This needs to be programmed in the SPI flash of your xCORE-AUDIO board.

Do we really need to make it?
I mean, with windows (after having instal driver) i have no problem to work with 32bits and when i read documentation our xmos can work natively with mac os in 32bits :/

It was just an idea to test if there is something about the device's descriptor that macOS doesn't like
