The UAC2 audio device is the XMOS reference board. This is what I'm observing. As soon as the XMOS board is plugged in to the USB port, the display on my DAC indicates that is has locked at 192kHz which is the maximum sampling rate supported by the XMOS. Is this the expected behavior or can I specify the defualt sampling rate at start up? Thanks
