https://bugs.gentoo.org/323379 (some history)

media-libs/libcanberra is still broadly used as sound event library, even 
media-video/pipewire[X] depends on it, and KDE Plasma packages as well.

media-libs/libcanberra has IUSE=+sounds, which currently pulls in x11-themes/
sound-theme-freedesktop. But it can be replaced by other sound themes as long 
as they adhere to freedesktop.org spec, which essentially seems to come down 
to standardised notification sound names and some index file in

/usr/share/sounds/<theme-name>/index.them

In KDE world there are two alternatives:
- kde-plasma/ocean-sound-theme
- kde-plasma/oxygen-sounds

But it is possible there are other themes already in ::gentoo that I am not 
aware of, or maybe other DE maintainers have their own ideas, so CCing 
relevant maintainers.

Current x11-themes/sound-theme-freedesktop RDEPENDs:

gnome-base/gnome
gnome-extra/gnome-tweaks
kde-plasma/kpipewire
kde-plasma/plasma-pa
media-libs/libcanberra-0.30-r7:sound

There are also a few media-libs/libcanberra[sound] revdeps that are addressed 
in the linked PR.
