Generic DAC on RPi - No Output devices


Using the “Generic DAC” driver, I have no selectable output. Even ALSA is missing from the dropdown.

My raspberrypi.conf is empty. aplay -l shows no soundcards.

How do I get this to work with a straight I2S DAC. (No need for I2C at all)

what output options do you have when you disconnect your dac? (before boot)

Hi. I looked at the source code, and from what I can tell, the “Generic DAC Driver” option doesn’t load the modules we would need. We’re using a PCM1974 chip. Can you confirm which modules would need to be loaded to connect to a 1794/1794a?
