I apologize. There is sound! I was looking for a sound card in yast as well as for the sound control widget on the system trey. Those are still not there. But there is sound! As far as the kernel is concerned, the bug is fixed. There is some update scripting needed - to modify the dtoverlay setting, to show the sound control widget, and to show a sound card in yast. But each of those should have a separate bug. Please file those separate bugs, as you know what needs to be done. You can close this one. Thank you!
