The dac+ zero will not be detected by the raspberry pi. I have followed the configuration guide for linux 4.x or higher. I have tried using a raspberry pi 3B+. It won't work with either. I have gotten this to work on a different pi with a dac+ pro. However, with a dac+ standard that I also have, and the dac+ zero I have had no luck. I've attached outputs of dmesg, sudo vcdbg log msg, and a snippet from my config.txt file. Help with be greatly appreciated!
