OK, now I am confused. This is the output of kldstat:

/boot $ sudo kldstat
Id Refs Address    Size     Name
 1   17 0xc0400000 a5eb64   kernel
 2    1 0xc0e5f000 2f08     speaker.ko
 3    1 0xc0e62000 a0d6f8   nvidia.ko
 4    3 0xc1870000 29b98    linux.ko
 5    1 0xc189a000 53cc     sem.ko
 6    1 0xc18a0000 6a4f8    acpi.ko
 7    1 0xc773f000 7000     linprocfs.ko

This is my 'loader.conf'

/boot $ cat loader.conf
speaker_load="YES"	# AT speaker module
nvidia_load="YES"	# Load nvidia driver
sem_load="YES"		# Load the sem module for firefox-35

# Superpages
vm.pmap.pg_ps_enabled=1.

I have sound compiled into my kernel:

# Sound
device		sound
device		snd_hda		# nVidia MCP51 sound support

When I attempt to unload the driver, I receive this message:

kldunload snd_hda
kldunload: can't find file snd_hda

Therefore, are you implying that I have to recompile my kernel without
the sound device and then load it manually when I boot up? That seems
like a bug in FreeBSD.
