Libcanberra is a simple abstract interface for playing event sounds. It implements the XDG Sound Theme and Naming Specifications for generating event sounds on free desktops, such as GNOME. Further description here

## Installation

Libcanberra can be installed with the package libcanberra. libcanberra no longer requires any backends for ALSA, pulseaudio or gstreamer, as they are now built in to the libcanberra package.

It is necessary to have a sound theme installed in order to hear any event sound:

- The default sound theme 'freedesktop' (sound-theme-freedesktop) will be installed as dependency of libcanberra.
- Alternatively, search for "sound-theme" in the official repositories or the Arch User Repository.

## Configuration

By default, the GTK module is loaded automatically when a GTK application launched. You can overwrite the default settings in the user's GtkSettings file:

    $HOME/.gtkrc-2.0 and $XDG_CONFIG_HOME/gtk-3.0/settings.ini

    gtk-enable-event-sounds=true
    gtk-enable-input-feedback-sounds=true
    gtk-sound-theme-name=freedesktop

In GNOME, these settings are managed by gnome-settings-daemon, and the configuration is available in GSettings under the `org.gnome.desktop.sound` schema.

## systemd

To enable bootup, shutdown and reboot sounds using canberra, enable `canberra-system-bootup.service`.
