Gtk-Message: 10:32:31.466: Failed to load module "canberra-gtk-module"

I installed matlab 2019a with update3 on ubuntu 16.04 64bit. When I run matlab, I got output: Gtk-Message: 10:32:31.466: Failed to load module "canberra-gtk-module".
How to sort this problem.
Thanks in advance.

For anyone still bashing their heads off the wall in 2020 on R2020b. I'm using Arch Linux on Gnome Xorg. Currently patched at Kernel 5.9.8. I installed from the MATLAB website and created a folder with user permissions in the default install folder. Then ran ./install.
Here's what i used.
I first had to install gtk-2 package from the official arch repos.
sudo pacman -S gtk-2 %it might have worked after this if i didn't mess with my java install so much trying to make it work
Next i had to rollback my java version...
java --version %I had absolutely blown away my java install at this point and grabbed many packages from AUR to no avail so i got the official repo package
sudo pacman -S jre8-openjdk % Installs java
sudo pacman -S jdk8-openjdk % Installs java
Finally set matlab to open with my known good/supported version
export MATLAB_JAVA=/usr/lib/jvm/java-8-openjdk/jre
matlab %%opens MATLAB window without issues or failures
% I can and did plot a polynomial just to make it work
% First plot polynomial code that shows up on google.
y_1 = @(x) -0.6729+4.8266*x-0.4855*x.^2+0.0312*x.^3
x_1 = 0:0.1:33.5;

The error message "Gtk-Message: Failed to load module 'canberra-gtk-module'" indicates that the GTK library is unable to load the "canberra-gtk-module" module. This module is related to the GNOME Sound Theme support and is often used for playing sound events in GTK applications.
To resolve this issue, you can do one of the following:
  1. Install the 'libcanberra-gtk-module' package:Depending on your Linux distribution, you can install the required package. For example, on Debian-based systems (such as Ubuntu), you can use the following command:
sudo apt-get install libcanberra-gtk-module
On Red Hat-based systems (such as Fedora), you can use:
  1. sudo dnf install libcanberra-gtk2 libcanberra-gtk3

So the answer is in a terminal excecute the following
sudo apt-get install libcanberra-gtk* libgconf-2-4
sudo ln -s /usr/lib/x86_64-linux-gnu/gtk-2.0/modules/ /usr/lib/
The second line will create a link to the module. Matlab works with gtk-2.0 module. For other linux distributions follow this.
Problem solved, at least for me.

Thank you!
It works on Ubuntu 22.04 too with Matlab R2021a

I believe the canberra-gtk-module messages have no detrimental effect on MATLAB and can be ignored, but having said that...
To run MATLAB R2019a or R2019b on Ubuntu 16.04 LTS without the canberra-gtk-message:
You have three environmental variables that need to be set before running matlab
export GTK_PATH=/usr/lib/x86_64-linux-gnu/gtk-2.0
export GIO_EXTRA_MODULES=/usr/lib/x86_64-linux-gnu/gio/modules
OR you can run matlab in the bash shell by typing:
$ GTK_PATH=/usr/lib/x86_64-linux-gnu/gtk-2.0 LIBOVERLAY_SCROLLBAR=0 GIO_EXTRA_MODULES=/usr/lib/x86_64-linux-gnu/gio/modules /usr/local/MATLAB/R2019a/bin/matlab
To run R2019a on Ubuntu 18.04 LTS without the canberra-gtk-message:
You need to install libcanberra-gtk-module and libgconf-2-4
You don't need to set any environmental variables.
To run R2019b on Ubuntu 18.04 LTS without the canberra-gtk-message:
you need to install libcanberra-gtk-module
You have one environmental variable that needs to be set before running matlab:
export GTK_PATH=/usr/lib/x86_64-linux-gnu/gtk-2.0
OR you can run matlab in the bash shell by typing:
$ GTK_PATH=/usr/lib/x86_64-linux-gnu/gtk-2.0 /usr/local/MATLAB/R2019b/bin/matlab
Good luck.

solution on arch was to export and set GTK_PATH to matlab executable

I did: sudo apt-get install libcanberra-gtk-module libcanberra-gtk0. But the error message is still there.

See bug reports:
"On some Linux distributions, a message appears in the terminal window when starting MATLAB:
Gtk-Message: <timestamp>: Failed to load module "canberra-gtk-module"
Gtk-Message: <timestamp>: Failed to load module "pk-gtk-module"
This message is informational and has no effect on MATLAB."

I tried the work around suggested in the "bug report" from the above link. Did not fix the problem. I can use the matlab as is with the error but irritating to keep the terminal open and running otherwise Matlab closes

I had the same error with my R2019b installation in ubuntu 19.10. After I installed the module with "sudo apt install libcanberra-gtk-module -y", if I call matlab from the command line with the cmd "LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/gtk-2.0/modules:$LD_LIBRARY_PATH /usr/local/bin/matlab", the error message doesn't appear anymore.

Finally I solve this problem by change from 2019b to 2019a. The error message disappear. There must be something wrong with 2019b's Linux version.

It had the same message and then I followed @Scott Minkin recommandation and I still have a message, but a different one:

In both case Matlab 2019b is launched as expected but I am wondering if everything is ok because of the messages I keep having in the Terminal.
I am running Ubuntu 19.10. Thank you for your expertise.

Not sure why the pk-gtk-module warning is coming up. What is the value of $GTK_MODULES? And can you try blanking it out by setting GTK_MODULES=
GTK_PATH=/usr/lib/x86_64-linux-gnu/gtk-2.0 GTK_MODULES= matlab
Good luck.

GTK_PATH=/usr/lib/x86_64-linux-gnu/gtk-2.0 GTK_MODULES = matlab
launch Matlab, and display
Failed to load module "pk-gtk-module"
in the console

I also get the same error message while running
Gtk-Message: 04:38:48.679: Failed to load module "canberra-gtk-module"
for Matlab R2020a on Ubuntu 19.10, it works slower than R2019b but untill now, during running the program, it does not give an another error.
