After installing IIO-Oscilloscope on Ubuntu following this link:
I can launch the application with ./osc in build folder
But I see the error which from the GTK module:
Gtk-Message: 10:19:52.992: Failed to load module "canberra-gtk-module"
LIBIIO version 2021_R2
My OS is Ubuntu 2020.LTS
Is there any problem with the GTK module? Did I need to install the new vesion of GTK (GTK3) instead of GTK 2?
