Bugzilla Bug 239847

Hello arches,

libcanberra is a new blessed dependency of GNOME. It provides a library for
portable event sound API, that implements the Freedesktop.org sound theme
specification. It can use either pulseaudio, alsa, gstreamer or a dummy null
driver to play themed sounds with that priority order of output methods
(pulseaudio can do glitch-free and positional event sounds, alsa doesn't
possibly loose some utilized hardware features, gstreamer supports resampling
on systems where ALSA and pulse is not available).
libcanberra will be a hard dependency on epiphany and (maybe optional in)
gnome-control-center and replaces the dreaded esound daemon in all remaining
GNOME usages in GNOME-2.24.

x11-themes/sound-theme-freedesktop is a default fallback sound theme for use by
sound theme supporting libraries and applications, currently only through
libcanberra.

As these packages will become the replacement of esound, gnome-audio and system
sounds in GNOME-2.24, please give them some keyword love.

You can test by installing both (libcanberra with USE=gtk) and using
canberra-gtk-play --id="<sound themed name>", where "sound themed name" is one
from the documented themable sounds at
http://0pointer.de/public/sound-naming-spec.html
However sound-theme-freedesktop supports only a subset of those, so basically
you can test with any .ogg file that sound-theme-freedesktop ships as the ID,
dropping the .ogg suffix. So canberra-gtk-play --id="desktop-login" should play
the default desktop login sound.

You can also test by running a gtk+ application, such as gtk-demo, with the
gtk+ sound events module provided by libcanberra[gtk], as follows on a
graphical terminal:

GTK_MODULES="canberra-gtk-module" gtk-demo
... with that various operations, such as clicking on buttons, minimizing,
maximizing, etc, should make sounds.

Hopefully all arches that have keywords on gnome-audio, epiphany and/or
gnome-control-center can add the keywords (the gtk+ event sounds can be useful
to everyone, GNOME users or not). This is a requirement for a full GNOME-2.24.

bug 240093 tells that if you use pulseaudio then event sounds with hyphens
won't be played until bug 240093 is solved. So you can test with something that
doesn't have a hyphen or not use pulseaudio - I don't think keywording should
be blocked by a pulseaudio case here, as this is just with one of the drivers,
and we are talking only of ~arch, not stabilization.

Please also re-keyword www-client/epiphany-2.24.0.1 (or newer if available by
then) when there's libcanberra. Epiphany-2.24 ebuild currently hard depends on
libcanberra, but if really necessary we can make it optional, even though
libcanberra is really tiny (89KB in total for main library, gtk+ library and a
good backend sound driver)

also www-client/epiphany-extensions-2.24.0 please, as it depends on
>=epiphany-2.24.0

for epiphany and epiphany-extensions I of course mean rekeywording if you have
keywords on previous versions - if not, I don't object adding keywords
regardless though ;)

This particular bug was introduced in pulseaudio-0.9.12. Pulseaudio-0.9.11-r2
works, as does pulseaudio-0.9.13.

~alpha/~ia64/~sparc done

Marked ~hppa.

ppc/ppc64, this is a notification that you just lost your keyword on
>=xchat-gnome-0.24 because of this bug.

~ppc64. i guess we are in a position to ~xchat-gnome but that also has a hard
dep on a newer gcc that we have stable.

Marked ~ppc.

I already did this for arm/sh
