4.18.0-240.22.1.el8_3.x86_64
Sound works as expected.
4.18.0-305.3.1.el8.x86_64
only "dummy output" shows up under the Sound Preferences on the desktop.
I guess there's a kernel bug somewhere that's causing the driver for that soundcard to not load?
The lshw command (when running kernel subversion 240.22.1, i.e. the "old kernel") tells me that it has this soundcard:
