First, what version of FreeBSD are you using?

Newer versions allow you to kldload the drivers, without rebooting and
without building a new kernel...older versions require you to build a new
kernel and reboot.

If I recall, all 4.x versions will require a kernel recompile, 5.x doesnt.

If supported, simply execute as root:

kldload snd_driver

And this will load /all/ supported drivers for all cards.  It's likely
that one of these will work. :)

You can add the following to /boot/loader.conf to do this at boot time:


Or, follow the directions in man pcm:

     For a card with bridge driver support, and a PnP card:
     device pcm

So, add
device pcm

to your kernel config file.  After building and booting the new kernel
(see the Handbook for how to do this):
  cd /dev; sh MAKEDEV snd0
to create the devices.
