That depends on how you enabled them :-) You should have something
like this in /var/run/dmesg.boot:

  pcm0: <nVidia nForce2> port 0xe400-0xe4ff,0xe800-0xe87f mem 0xeb000000-0xeb000fff irq 21 at device 6.0 on pci0
  pcm0: <Avance Logic ALC655 AC97 Codec>

In this case, you should add to your /boot/loader.conf (creating the
file if it doesn't exist):

  snd_ich_load=YES

As I say,

I'd look in the PCI device configuration first.

It might also help to move to 6.1.  I had problems with sound on this
board until I did.
