Has anyone tried to get it running with Raspbian Buster? I am beating my head against it right now and so far, have nothing but confusion.

I have AudioInjector. Setup is done following your instructions step by step.
Raspberry PI3 B+.

The card is discoverable by system.

Keep having this
aplay: pcm_write:2053: write error: Input/output error

dmesg:

i2c_arm and i2s interfaces are on

Linux raspberrypi 4.19.75-v7+ #1270 SMP Tue Sep 24 18:45:11 BST 2019 armv7l GNU/Linux

Any suggestions where is the mistake on my side?

Thank you in advance,
Victor
