gnome sound A small and lightweight implementation of the XDG Sound Theme Specification (http://0pointer.de/public/sound-theme-spec.html). Enables ALSA sound driver. Enables gstreamer sound driver. Not useful when alsa or pulseaudio is available. Enables building of gtk+ helper library, gtk+ runtime sound effects and the canberra-gtk-play utility. To enable the gtk+ sound effects add canberra-gtk-module to the colon separated list of modules in the GTK_MODULES environment variable. Enables PulseAudio sound driver that should be able to support positional event sounds. This is the preferred choice for best sound events experience and picked by default if compiled in and possible to use at runtime. Enables Trivial Database support
