Thanks to everybody for your suggestions!
I just found something on YouTube about running one of those cards.
All I needed to do was adding this line to /boot/config.txt
dtoverlay=hifiberry-dacplus
(I had already commented out the onboard soundcard . . . )
Finally it shows up as a alsa sound device as it should.
Not sure if this one is the best choice - I'm still waiting for an answer from the manufacturer.
Now I can keep moving on with my sound module!
The hardware is working as expected or even better.
(Still discovered a kernel compilation omission, though . . . )
Cheers :)

hi,
maybe these tutos, about configuring an I2S sound card on a Pi, can help you:
https://learn.pimoroni.com/article/raspberry-pi-phat-dac-install
https://learn.adafruit.com/adafruit-i2s-audio-bonnet-for-raspberry-pi/raspbe...
Not sure their pre-configurated scripts will work with your hardware, but maybe they will after all.

It does appear as a sound card and you can connect to it as a MIDI device via aconnect.

The PiSound looks great but would require a different housing. Mmmmhhh . . . How does Pd communicate with it? Does it show up as a sound card and MIDI device?

I can confirm that the Pisound works great, but it's not a cheap solution.

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 wonder if anybody made a "virtual soundcard" that talks to the RPi GPIO and shows up as a ALSA device.
I have a very small Sounblaster card that works fine and sounds ok but it's still too large to fit inside. With the internal headphones out my software doesn't even start up.
I'm afraid that this won't even work at all with Pd . . . Has anyone ever used any of these RPi DACs?

Hi everybody!
I just got a DAC expansion board for my RPi4 but Pd doesn't see it.

Since there is no room for a sound card in such a small box and the RPi headphone out is no good it looks like the only compact way.
Can anybody point me to instruction for making Pd use these DAC expansion boards as a sound card?
What do the commands $ pd -listdev $ $ cat /proc/asound/cards tell you about available cards?
What does the manufacturer of the expansion board tell you about it? Will it be a separate sound card from the built-in one? Or will the
expansion
merely provide the built-in one with more channels?
