Hi,
I just followed the guide for 3.18+ and yet, my card would not show up in Kodi and would only come at the end of the list when running aplay -l.
I found in another of your answers on the forum that you have to disable de board's chipset with dtparam=audio=off. That solved my problems obviously.
Please, add it to the guide so that others don't fall in the same situation :)
Thank you
