It did not work when I tried it. Here is a snippet from /etc/init.d/alsa (alsa-utils 1.0.14-1):

case "$1" in
  unload)

        unload_modules all || exit $?
        ;;
  reload)
        EXITSTATUS=0
        unload_modules all || EXITSTATUS=1
        load_unloaded_modules || EXITSTATUS=1
        exit $EXITSTATUS
        ;;

------------------------------------------------------------------------

The first part is fine: alsaconf calls "/etc/init.d/alsa unload", which unloads all sound modules and saves a list of the module names in /var/run/alsa/modules-removed (if /var/run/alsa/ exists). The problem is that unload_modules starts out by zeroing the list of modules whenever it is called (:> /var/run/alsa/modules-removed). Therefore, if you run "/etc/init.d/alsa reload" while no sound modules are loaded then it will generate an empty list of removed modules and then it will proceed to reload every single module on that list. Just try this on an up-to-date Sid: Do an alsa "unload" followed by a "reload". [1][2]

The old version of alsaconf did "modprobe $DRIVER" directly which worked as long as it managed to figure out the correct name of the main sound module. Now it calls the alsa startup script with the undefined action "restart" and you get the error that Raju reported. However, "reload" would not work either.

[1] I dare you, I double-dare you!

[2] I just realized that udevtrigger with the subsystem match does not

    work reliably to reload the sound modules on my system. I have to     run udevtrigger without this option to get the modules loaded again.
