Honestly, this could potentially go a lot of different directions;
software/driver(s)/setup...
It might be helpful to get the pinouts. The kernel
(dmesg(8)) will provide it for you. You can see them by;
loader.conf(5)
adding the following to /boot/loader.conf:

boot_verbose="YES"

or by simply selecting boot verbose on the loader menu
6 --> boot verbose

and then getting the results from dmesg(8)
/var/run/dmesg.boot

If everything looks as anticipated, you might check that
your software is using the right sound system (OSS).
I've had very good experiences on these sound systems by
installing
audio/xfce4-mixer
doing so, always seems to get the correct settings for
everything on these boards -- even if you never use
the application.
Because these boards can be so troublesome where sound
is concerned; I used to have a script that would both
check, as well as set everything up. But I can't seem
to locate it ATM.
