    6 In order to facilitate saving and restoring of soundcard mixer levels at
    7 shutdown and boot, take these two methods as examples:
    8 
    9 
   10 ***NOTE***
   11 BOTH methods require that you store your mixer levels beforehand, use
   12 '/usr/sbin/alsactl store' first!
   13 **********
   14 
   15 
   16 Method 1: /etc/modprobe.conf
   17 
   18 Add something like the following to /etc/modprobe.conf:
   19 
   20 ----
   21 # ALSA mixer settings save/restore
   22 install snd-emu10k1 /sbin/modprobe --ignore-install \
   23 	snd-emu10k1 $CMDLINE_OPTS; /usr/sbin/alsactl restore
   24 remove snd-emu10k1 /usr/sbin/alsactl store; /sbin/modprobe -r \
   25 	--ignore-remove snd-emu10k1
   26 ----
   27 
   28 (As with the other READMEs replace 'snd-emu10k1' with the correct
   29  soundcard module for your system.)
   30 
   31 (On some hardware it seems the kernel module gets loaded but the
   32  soundcard isn't initialized in time for the modprobe.conf install
   33  command to succeed. If this is the case for your hardware, try
   34  method 2 instead.)
   35 
   36 
   37 Method 2: /etc/rc.d/alsa init script
   38 
   39 Add "alsa" to the SERVICES array in /etc/rc.conf.
