   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.
