I guess I'll try to find out from the manufacturer if they know how to do it. I had already contacted the store where I bought it if they have any idea. I don't even know if the DAC is made by ARGON or by a 3rd party manufacturer. There's no documentation other than "Install Volumino".
I wonder if anybody made a "virtual soundcard" that talks to the RPi GPIO and shows up as a ALSA device.
This would be so complicated that I don't expect the manufacturers to
force
you to do this.
Not sure if it would be so complicated - of course for me it would definitely be too difficult to do, though. I think that all of those DAC expansion boards talk to the same pins. Once it's done it should be rather universal. But probably each manufacturer does its own thing - as usual!

cat /proc/asound/cards says --- no soundcards --- Pd doesn't see any soundcards.
I think the problem is that the DAC get its data from the GPIO pins that Pd cannot communicate with.
I would ask the manufacturers of this https://www.berrybase.de/en/new/argon-nanosound-one-case-f-252-r- raspberry-pi-4?c=2389 how their sound card can be accessed or if specific drivers (called
"Modules"
in linux) have to be loaded.
