peachtree shift usb dac

I am trying to use a peachtree shift usb dac (ES9010K2M chipset) with volumio 2 on my raspberry pi v1. The dac works for the most part, but there is a lot of crackling in the sound that I can’t seem to fix. I’m fairly sure it is not caused by the raspberry pi itself since my audioquest dragonfly sounds fine. Does anyone have some advice on how to go about debugging this issue?
