Well, I'm only able to share my own experiences. The 3 with Realtek
chips, all make a light pop sound during boot. The one I happen to be
writing this from emits the following in dmesg(8)

hdacc0: <Realtek ALC1200 HDA CODEC> at cad 0 on hdac0

sysctl(8) reports:
hw.snd.default_unit: 0

I have sound. That's as much as I can offer.

All the best.
