It’s not that simple I’m afraid. The fact that ‘XMOS works with Linux’ is not enough. That basically means it will do DoP out-of-the-box.
For native DSD it means that the device manufacturer needs to program the USB controller ‘in the right way’ to be able to get a patched Linux kernel that supports native DSD.
I can help out with creating the patch, so … do you have access to a linux system? So we can get necessary information on the DAC itself if the firmware is capable of delivering native DSD on Linux?
