Yes, you are right. Yesterday I was messing around with the environment
variable GTK_MODULE. I guess that confused me. Having undefined it now I
only see reference to gtk-3:

In the mean time I've found out the existence of a simple test program
called canberra-gtk-play in the libcanberra package. With this I tested
that I can actually play a sound, but it gives the same message:

$ canberra-gtk-play -i phone-incoming-call
Gtk-Message: Failed to load module "canberra-gtk-module"

After playing somewhat with GTK_PATH I've found that if I set it like
shown below I do not get the warning message:

$ GTK_PATH="/home/beffa/.guix-profile/lib/gtk-3.0"
/gnu/store/cd8x9llkvfj29rwzd455a7pf0fq6kwnl-emacs-canberra-24.3/bin/emacs
GLib-GIO-Message: Using the 'memory' GSettings backend.  Your settings
will not be saved or shared with other applications.

$ GTK_PATH="/home/beffa/.guix-profile/lib/gtk-3.0" canberra-gtk-play
-i phone-incoming-call

However, with the official emacs package I still get it:

$ GTK_PATH="/home/beffa/.guix-profile/lib/gtk-2.0" emacs
Gtk-Message: Failed to load module "canberra-gtk-module"
GLib-GIO-Message: Using the 'memory' GSettings backend.  Your settings
will not be saved or shared with other applications.

$ GTK_PATH="/home/beffa/.guix-profile/lib/gtk-3.0" emacs
(emacs:7105): Gtk-WARNING **: GTK+ module
/home/beffa/.guix-profile/lib/gtk-3.0/modules/libcanberra-gtk-module.so
cannot be loaded.
GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same
process is not supported.
Gtk-Message: Failed to load module "canberra-gtk-module"
GLib-GIO-Message: Using the 'memory' GSettings backend.  Your settings
will not be saved or shared with other applications.

So, I've rebuilt emacs without libcanberra, but with gtk-3 with the
attached recipe and now the message is gone:

$ GTK_PATH=/home/beffa/.guix-profile/lib/gtk-3.0
/gnu/store/4y7ic831rbawm96qb1n4da19x9qlwk73-emacs-gtk3-24.3/bin/emacs
GLib-GIO-Message: Using the 'memory' GSettings backend.  Your settings
will not be saved or shared with other applications.

So my conclusion is:

Given that libcanberra is built with gtk-3 and emacs builds fine with
gtk-3, I would suggest to change gtk version in the emacs package
(I've also added --with-x-toolkit=gtk3 as flag to configure. Not sure
if this is really necessary).

In addition, it would be nice not to have to define GTK_PATH. I guess
that would require some modification to either libcanberra or the gtk
package.

On a side note, I built a couple of variants of emacs-canberra. After
a while I wanted to check which one is the most recent one with

$ ls -l /gnu/store/*emacs-canb*

and have found out that all files in the store have a time stamp of "1
Jan 1970". Why is guix not producing the expected time stamps?

Fede
