I am trying set up a DAC+ on a Raspberry Pi 3 with jumper-cables for testing.
I connected 3.3v, 5v, Gnd and GPIOs 18, 19, 21 and Pins 27+28:
But there is no sounddevice found:
pi@raspberrypi:~ $ aplay -l
aplay: device_list:268: no soundcards found...
I ran a PCM5102 on i2s before that in similar configuration on GPIO 18,19 an 21 an that worked out fine.
Raspberry is up to date: Linux raspberrypi 4.4.8-v7+
Any idea how to fix this? Do I need to connect I2C as well? I have something connected to this, so I did not try this.
