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 :) Ingo From: Pd-list [mailto:[email protected]] On Behalf Of Antoine Rousseau Sent: Thursday, September 23, 2021 5:57 PM To: Pd-list Subject: Re: [PD] How to use a DAC expansion board with the RPi4 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/raspberry-pi-usage Not sure their pre-configurated scripts will work with your hardware, but maybe they will after all.
