I'd like to propose a different approach.  This is a slight
modification of what I do on my own boxes (using a script in
/usr/local/etc/rc.d).

rc.conf (example):
   mixer_enable="YES"                   # (default = NO)
   mixer_config="/etc/mixer.conf"       # (default)
   mixer_device="/dev/mixer"            # (default)

mixer.conf (example):
   # some comment
   vol     90
   synth   50   # more comments...
   bass    75
   treble  50
   mic      0
   line    50
   cd      80
   speaker  0
   igain   50
   ogain   70

rc:
   if [ "X${mixer_enable}" != X"NO" -a -f "${mixer_config}" ]; then
           echo -n ' mixer'
           slots=`mixer -f ${mixer_device} | cut -d' ' -f2 | tr '\n' '|'`recsrc
           sed 's/#.*$//' ${mixer_config} | egrep "$slots" | xargs mixer -f ${mixer_device}
   fi

Just my 0.02 Euro...

Regards
   Oliver
