It has a simple DAC called toonie. And the driver for this is missing. If the codec is missing, the mixer device is also missing. It is enough when you have: device sound # Generic sound driver (required) device snd_ai2s # Apple I2S audio If you have an external USB gadget then you can use snd_audio. Works fine with low-cost (high-quality) usb-ad/da. Andreas
