This should work when changing the volume with hardware volume keys,
because we are using gnome-settings-daemon's media keys plugin. (Maybe
we didn't back when this bug was filed.)

I don't think the sound menu should emit these sounds when changing the
volume with the volume slider.

Title:
  volume change sound effect (audio-volume-change) does not play when
  volume is changed

Status in Sound Menu:
  Won't Fix
Status in “indicator-sound” package in Ubuntu:
  Won't Fix

Bug description:
  Binary package hint: indicator-sound

  First of all, a quick introduction to the (unfortunately not very
  well-known) component we have had for a few releases now, called
  libCanberra, which is used for sound events in the same style as
  icons.

  In upstream GNOME, any time an application changes the system volume
  it plays the "audio-volume-change" sound effect. This is done per
  application, using ca_gtk_play_for_widget.

  The sound is unimplemented in Ubuntu's default sound theme, but
  absolutely exists in most others. (FreeDesktop and Moblin are the two
  we should particularly care about, since they are available for
  installation in Lucid). With the FreeDesktop theme, it constitutes an
  _extremely_ helpful "pop" noise to indicate how loud the volume now
  is.

  Here is some sample code from gnome-settings-daemon ./plugins/media-
  keys/gsd-media-keys-manager.c in the update_dialog function:

  ca_gtk_play_for_widget (manager->priv->dialog, 0,
      CA_PROP_EVENT_ID, "audio-volume-change",
      CA_PROP_EVENT_DESCRIPTION, "volume changed through key press",
      CA_PROP_APPLICATION_ID, "org.gnome.VolumeControl",
      NULL);

  The same is also used for the upstream volume control applet. Although
  it only affects users with different sound themes, losing this feature
  is a regression. (And limits what can be done with Ubuntu's own sound
  theme, if that gets updated at some point).

  Please implement this feature in indicator-sound when a volume change
  is triggered.
