Justboom digi with rpi zero not working, no clue what to do

I am not getting any audio out of my Justboom digi zero (into a Schiit modi) from either coaxial or optical.
usb out works fine.

Error: “Failed to open ALSA device “hw:1,0”: No such file or directory.”

Things I have tried so far:
Factory reset
turn off i2s, reset, turn on, reset
looked in config.txt, seems correct (dtoverlay=justboom-digi)
I have updated to latest dev build
replaced justboom digi with a fresh unit (in case the first was DOA)
tried selecting different dacs in ui (generic i2s, Justboom dac, justboom amp)

I can’t seem to get anything to work, and I’m about ready to give up :frowning:

Here’s my log file: logs.volumio.org/volumio/WIQ4vjf.html

Anyone know how to resolve this?

{Edit, here’s aplay -l output}
aplay -l

If anyone is wondering, I have not found a solution to this issue yet :cry:
