On Ubuntu 24.04 you need to install libcanberra-gtk-module for gtk2 sound support. You will only see that error from gtk2 apps. gtk3 apps use libcanberra-gtk3-module which is preinstalled.

I do not understand what you’re saying.

I have the packages you mentioned installed on Ubuntu 24, but I still see that error in the syslog:

firefox[6710]: Failed to load module "canberra-gtk-module"

What’s wrong?

@Keith,

Thank you for your comment. It’s true that libcanberra is deprecated on Wayland-based systems, which includes the newer versions of Ubuntu like 23.* and 24.04. As you mentioned, it can cause confusing and irrelevant errors.

To resolve these issues on Ubuntu 23.* and 24.04, you can try removing libcanberra if it’s causing problems:

sudo apt remove libcanberra-gtk-module libcanberra-gtk3-module

Alternatively, if you still need the functionality provided by libcanberra, you can install the necessary packages to ensure compatibility:

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

However, if you’re using Wayland, it’s often best to rely on more up-to-date libraries and frameworks designed to work seamlessly with it.

Thanks again for bringing this to our attention!
