CentOS 8 Sound driver for HP Elitebook 850 G6

I've been having a lot of trouble getting media to play on my HP Elitebook 850 G6, which is running CentOS 8. A Google search got me playing videos, but no sound. I didn't get any missing codex messages, so at this point I'm assuming that the problem is a missing driver for the sound system, or something like that.

Any ideas how I can solve this one?

TIA, Matt
