[AudioI] read error

I noticed some weirdness and decided to start with a fresh Bullseye image.
After a full-upgrade I made the changes mentioned on the git page. The
devices show up when listed, but I cannot get the speakers or microphones
(on-board) to work. It seems like the device is seen but not really set up.
Thanks in advance for any help you can provide.
aplay and arecord see the device:
pi at soundpi:~ $ arecord -l
**** List of CAPTURE Hardware Devices ****
card 0: audioinjectorul [audioinjector-ultra], device 0:

But even though I can see them, I don't seem to know how to use them. I
get an error trying to play on card 0 that gives an interesting error that
may point to a config or software issue:
