Compiling in sound driver in kernel

[Carmel]

This is my first attempt to compile in a driver in a new kernel I am
attempting to build.

Using loader.conf, I have the 'snd_hda' driver presently being loaded.
I want to compile it directly into the kernel. I tried this:

device	snd_hda		# Sound driver

Unfortunately, the kernel will not build. What is the proper way to
build a kernel with sound embedded into it?

Thanks!
