usbdac sound card

 
Overview

I have been doing this for a long time, but it has not been successful. There is no sound after soldering, but the pcm2706 should be working normally. There may be a problem with the DAC. If someone finds the problem, please kick me. Thank you!Before, there was no sound when the power was turned on.

Newly drawn but not verified yet
