    Recently I got this RK3188 SOM and trying to boot from SD card and NAND. It works fine with the pre-built images.

My actual requirement is to connect the external USB sound card and play some audio on it. When I run the command "lsusb", it sows the USB Sound Device but either ALSA or Pulase audio is not recognising it as a sound device. aplay doesn't show it. Can you please help in this to resolve this problem;.

Waiting for your quick support.
