it'd be better to simply add to /boot/loader.conf.local (or loader.conf , i
prefer to have it clearly defined)
{DRIVER}_load="YES"
eg, for my Intel HDA i have
snd_hda_load="YES"

either
1) have a script that sets your levels . mine is saved by the OS,, but
sometimes i need to do it by hand, so i use this script:
[betom@ayiin] [Tue Sep 18 10:23:27 2007]
/usr/home/betom
$ cat bin/set_mixer.sh
#!/bin/sh
## Feedback fixed!!! mic == 0
mixer vol 86:86 pcm 86:86 speaker 49:49 mic 0:0 cd 40:40 rec 100:100 =rec mic
--
of course, your device may be different, so adjust accordingly.
2) to save the values, check /etc/rc.d/mixer. mixer_save is called on stop, so
a) set your levels
b) add to /etc/rc.conf
mixer_enable="YES" # Run the sound mixer.
c) run /etc/rc.d/mixer stop
d) reboot + verify they are set to the right thing. In theory, they should be
saved everytime to reboot..
( i just realised i dont actually have that line in rc.conf...but my levels are
kept across reboots..so all is good... :)

use /boot/loader.conf.local
