Not an expert, but I would expect that you don't have to load anything to make sound work.

Anyway, while there isn't a system with your exact hardware, there are
two probes in the unofficial FreeBSD hardware database that are reasonably close:
https://bsd-hardware.info/?view=search&vendorid=8086&deviceid=51c8&subvendorid=1028#list

Maybe looking at their dmesg and kldstat helps you

Best of luck,
