Sorry for the late answer. In my case, the sound was the correct one, but it was played twice at the same time, causing some unpleasant saturation.
Furthermore, if I changed the sound in the Gnome control panel, than I would have two different sounds playing at the same time (the newly configure Gnome sound, plus the old one, played by module-x11-bell). That being said, I have not tried it on a fresh disco install. Mine was installed a year ago, and upgraded to disco... It took me that much time to investigate the problem and report it ;-) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1827842 Title: pulseaudio should not load module-x11-bell in gnome-shell Status in pulseaudio package in Ubuntu: Triaged Bug description: The package `pulseaudio` installs a startup script in `/etc/xdg/autostart/pulseaudio.desktop`, which itself runs `/usr/bin/start-pulseaudio-x11`, which loads a number of x11 related modules in `pulseaudio`. One of these modules is `module-x11-bell`, which makes `pulseaudio` play a sound each time a system bell is emitted (usually by terminal applications, such as bash or vim). This is redundant with gnome-shell, which is also able to handle the system bell (through the gsetting key `org.gnome.desktop.sound event-sounds`). The gnome system bell is directly configurable by the user (Settings > Sound), so it should be preferred over pulseaudio's own system bell. I suggest to patch the `/usr/bin/start-pulseaudio-x11`, to avoid loading `start-pulseaudio-x11` if it detects it is running in Gnome Shell (e.g. if GNOME_SHELL_SESSION_MODE is set).
