Alsa is already ported to the Rock4SE kernel. I was hoping I could get the audioInjector zero overlay, so I could use it as a starting point to write an overlay for the Rock4SE (and A,B). However, I have no experience with that, so if you were interested in writing one I would be very happy with that! I’m also working on trying to write one for raspberrypi 7-inch touchscreen for the Rock4.
The OS I am using is dietpi v8.15 from the Radxa website:
However, with their debianOS distro, they already had an overlay installed for the rpi touchscreen, so I may go back to that. I just don’t care for DKE and that OS is all KDE.
