DAC smsl c100 not work with volumio

Is it possible that it’s not compatible? It doesn’t recognize it.
Is there anything I need to do to add it?
I use Raspberry 4 now


How are you delivering power to your DAC?

Have you check Raspberry Pi 4B USB power delivery capabilities?

5 amp stabilized power supply for the Raspberry.
the DAC is connected to the Raspberry USB

Is there anything else connected to the USB ports?
