I just figured out that Radxa has already created an overlay for the audioinjector soundcards for their Debian11 OS. Their website is a bit fragmented, so I just found it. I’ll give that a try and see if I can get both the sound card and the touchscreen working. Then just one more major issue to resolve: convince Bluewave Studio to make their OpenAuto Pro work on the Radxa4SE, since getting a rpi4 in today’s world requires a home equity mortgage. :)

I appreciate the responses very much. Thanks.

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.

The website is:  https://wiki.radxa.com/Rock4/downloads
