[Natty] system-ready and login sounds do not play

[Harry]

Since the libcanberra upgrade version 0.26-1ubuntu6 (and up to the newest version 0.26-1ubuntu9) the system ready and login sounds do not play anymore.
The package gnome-session-canberra should use canberra-gtk-play from libcanberra to play those sounds.
Now I cannot find anymore the executable "canberra-gtk-play" file.
It should be in the directory /usr/bin.

However, if I install the package libcanberra-gtk3-0, that file is installed (then the ready and login sounds do play)
But then again, there is no package (except mutter) depending on libcanberra-gtk3-0.
Also libcanberra-gtk3-0 pulls in libgtk3.0-0 and libgtk3.0-common.

This is a bug, should the executable "canberra-gtk-play" be also found in the package libcanberra-gtk0.

[Harry (harry33)]

Right, I have investigated this bug further.

Because Natty does not have gtk+3.0 as a default installation, packages libgtk3.0-0 and libgtk3.0-common are not installed.
This creates a problem concerning libcanberra.

To be able to play system-ready (drums) and login sounds, an executable file "canberra-gtk-play" must be installed
(into the folder /usr/bin).
The latest libcanberra_0.26-1ubuntu9 installs it only with the package libcanberra-gtk3-0.
However, libcanberra-gtk3-0 depends on libgtk3.0-0.

So, without libcanberra-gtk3-0, it would be possible to install the executable "canberra-gtk-play" with the package libcanberra-gtk-0.
This is how it was done in the version libcanberra_0.25-0ubuntu1. In the later version the file was removed.

OK, to test this (this is also a workaround),
first check, that libcanberra-gtk3-0 is not installed.
Then copy (backup) the file "canberra-gtk-play" from the package libcanberra_0.25-0ubuntu1.
Then, install the latest version libcanberra_0.26-1ubuntu9 (this way "canberra-gtk-play" is not in your system).
Lastly copy paste the file "canberra-gtk-play" into the original folder /usr/bin.

Now the system-ready and login sounds are back.

Note that this bug does not influence event sounds (libcanberra-gtk-module).

Thanks Harry for the great analysis!

Robert, it seems the packaging dropped canberra-gtk-play recently? Can you please put it back? Thanks!

[Harry (harry33)]

Martin and Robert,

Am I wrong to presume that "canberra-gtk-play" was dropped from package libcanberra-gtk-0 when libcanberra was upgraded to 0.26 series and got the GTK+3.0 support?
Because, it seems that it was exactly the moment when "canberra-gtk-play" was introduced into the package libcanberra-gtk3-0.
That one was of course built against GTK+3.0 and so libcanberra depended on libgtk3.0-0.

Now, even though GTK3 package libcanberra-gtk3-0 is not needed right now in ubuntu, there may be issues,
if both packages libcanberra-gtk-0 and libcanberra-gtk3-0 contain the executable "canberra-gtk-play" as it is installed into the very same folder /usr/bin/ .

What is really needed her is canberra-gtk-play in both binaries, and under different names, however that would require the desktop files in gnome-session-canberra to have 2 different versions as well. I think we're best off getting canberra-gtk-play built against GTK2 only at this point, and since we will be moving closer to GTK3 in natty+1 then things should sort themselves out from there.

I agree.

I changed the status of this bug report.
This was because I cannot confirm it is fixed.
However, the executable canberra-gtk-play is now installed into the correct folder.
It is just that it won't play. I still cannot hear system-ready nor login sounds.
This makes me believe that another bug has been introduced with this upload (0.28-0ubuntu1).
Once again the workaround I have described above works, up to the version 0.26-1ubuntu10.

I can see from Launchpad, that this version has already been superseeded because of incompatible settings system.
The newest build (0.28-0ubuntu2), however, failed to build.

[Harry (harry33)]

The newest update of 0.28-0ubuntu3 works OK.
So this bug is fixed now.
