CentOS - Jun 2021 - Sound card disappears on Acer laptop with latest kernel

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:
