Hello!
There is a section in the above guide on how to integrate codecs with the Tegra audio driver. The device-tree and Tegra audio machine driver need to be updated to work with the codec. Please see the following for more details …

https://docs.nvidia.com/jetson/l4t/index.html
But unfortunately, I found that the function "snd_soc_register_card()" failed in the followi…
