I have installed Debian 11 from https://wiki.radxa.com/Rockpi4/downloads on my new Rock 4 SE card. Everything went good and works nice except sound out.
Try to listen through the 3.5mm jack for Radio Paradise webb music.
I can see the sound level changing in the Volume Control window. There is a speaker symbol with text “Dummy Output”.
Can’t attached picture on what it’s look like playing, Volume Control window.
Please help
