Armbian is a community driven open source project. Do you like to contribute your code?

Myself.  i am not so professional these things.

If you can show hot to add dts file. May be would be good. or if somebody add this to armbian so we can update.

 

BY the way when i do cat /proc/asound/modules i got these results below
 0 snd_soc_simple_card
 1 snd_soc_simple_card
