[PD] How to use a DAC expansion board with the RPi4

[Ingo]

Hi everybody!

 

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

https://www.berrybase.de/en/new/argon-nanosound-one-case-f-252-r-raspberry-p
i-4?c=2389

 

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?

They obviously don't show up in the ALSA sound options by default.

 

Thanks!

Ingo
