README for alsa-utils
In order to facilitate saving and restoring of soundcard mixer levels at
shutdown and boot, take these two methods as examples:
***NOTE***
BOTH methods require that you store your mixer levels beforehand, use
'/usr/sbin/alsactl store' first!
**********
Method 1: /etc/modprobe.conf
Add something like the following to /etc/modprobe.conf:
----
# ALSA mixer settings save/restore
install snd-emu10k1 /sbin/modprobe --ignore-install \
snd-emu10k1 $CMDLINE_OPTS; /usr/sbin/alsactl restore
remove snd-emu10k1 /usr/sbin/alsactl store; /sbin/modprobe -r \
--ignore-remove snd-emu10k1
----
(As with the other READMEs replace 'snd-emu10k1' with the correct
soundcard module for your system.)
(On some hardware it seems the kernel module gets loaded but the
soundcard isn't initialized in time for the modprobe.conf install
command to succeed. If this is the case for your hardware, try
method 2 instead.)
Method 2: /etc/rc.d/alsa init script
Add "alsa" to the SERVICES array in /etc/rc.conf.
