I've connected a speaker module (Hifiberry DAC) to the Rpi via I2S and it's working ok.
Now I'm trying to connect a microphone also via I2S. What I did was following the instructions in the following page:
https://learn.adafruit.com/adafruit-i2s ... g-and-test
Somewhere in the middle, it says:
But in dmesg I get:Download the module, written by Paul Creaser
git clone https://github.com/PaulCreaser/rpi-i2s-audio
make -C /lib/modules/$(uname -r )/build M=$(pwd) modules
sudo insmod my_loader.ko
Verify that the module was loaded:
lsmod | grep my_loader
dmesg | tail
It seems that the mic is trying to bind to the same sound card the speaker is bound to. What can I do? Is there another option to connect both mic and speaker to I2S?bcm2835-i2s 3f203000.i2s: Trying to bind component to card "snd_rpi_simple_card" but is already bound to card "snd_rpi_hifiberry_dac"
