Speaker tests in Settings/Sound/Output/Output Device need: media-libs/libcanberra[pulseaudio,sound] pulseaudio for the functionality and sound (the default) to bring in x11-themes/sound-theme-freedesktop which provides the sound files used (gnome-control-center code does not specify the filename, this is computed in libcanberra). I suggest the gnome-control-center ebuild should have this dependency, it is not obvious.
The ebuild does depend on media-libs/gsound which depends on media-libs/libcanberra, but without [pulseaudio,sound].
