I have /lib/udev/rules.d/90-alsa-restore.rules:
ACTION=="add", SUBSYSTEM=="sound", KERNEL=="controlC*", KERNELS!="card*",
GOTO="alsa_restore_go"
GOTO="alsa_restore_end"
LABEL="alsa_restore_go"
TEST!="/etc/alsa/state-daemon.conf", RUN+="/usr/sbin/alsactl restore
$attr{number}"
TEST=="/etc/alsa/state-daemon.conf", RUN+="/usr/sbin/alsactl nrestore
$attr{number}"
LABEL="alsa_restore_end"
But I don't have /etc/alsa/state-daemon.conf.
