Failed to load module “canberra-gtk-module” .... but already installed

Gtk-Message: Failed to load module "canberra-gtk-module"

but I already have the libcanberra-gtk-module and libcanberra-gtk3-module installed. (i.e. I tried this solution, but it is already installed.)

This happens for instance, when I run ipython --pylab

I'm running Ubuntu 13.04 - raring.

install gtk and gtk3 module should solve it.

sudo apt install libcanberra-gtk-module libcanberra-gtk3-module

This problem may occur on a 64-bit machine when one installs 32-bit software that requires canberra-gtk-module. acroread, for example, can cause this problem. In this case, the solution is to install the 32-bit version:

sudo apt-get install libcanberra-gtk-module:i386

One should leave the 64-bit version as well as it is necessary for 64-bit programs which attempt to use it.

I had the same problem and solve it with the solution given in this launchpad issue.

sudo apt-get install --reinstall libcanberra-gtk-module

Maybe too much but this solved my problem:

$ sudo apt-get install libcanberra-gtk*
