First select an ogg sound for startup sound, an example here startup sound is desktop-login.oga .
Put your sound to the /usr/share/sounds/freedesktop/stereo/ directory as: /usr/share/sounds/freedesktop/stereo/desktop-login.oga
/usr/share/sounds/freedesktop/stereo/libcanberra-login-sound.desktop /usr/share/gnome/autostart/libcanberra-login-sound.desktop file is required to play the sound at startup.
libcanberra-login-sound.desktop:
[Desktop Entry]
Type=Application
Name=GNOME Login Sound
Comment=Plays a sound whenever you log in
Exec=/usr/bin/canberra-gtk-play --id="desktop-login" --description="GNOME Login"
OnlyShowIn=GNOME
AutostartCondition=GSettings org.gnome.desktop.sound event-sounds
X-GNOME-Autostart-Phase=Application
X-GNOME-Provides=login-sound
Its do execute:
/usr/bin/canberra-gtk-play --id="desktop-login" --description="GNOME Login"
But sometimes it doesn’t work properly. canberra-gtk-play says:
Failed to play sound: File or data not found
Journalctl log says:
canberra-boot[4278]: Failed to play event sound: Not available
For solve this problem put this code to Exec line:
/usr/bin/canberra-gtk-play --file="/usr/share/sounds/freedesktop/stereo/desktop-login.oga" --description="GNOME Login"
What did we do here? We specified the Ogg file directly to the service. --file=""
After applied the libcanberra-login-sound.desktop file look like:
[Desktop Entry]
Type=Application
Name=GNOME Login Sound
Comment=Plays a sound whenever you log in
Exec=/usr/bin/canberra-gtk-play --file="/usr/share/sounds/freedesktop/stereo/desktop-login.oga" --description="GNOME Login"
AutostartCondition=GSettings org.gnome.desktop.sound event-sounds
X-GNOME-Autostart-Phase=Application
X-GNOME-Provides=login-sound
Now everything ok. Finaly, enable the canberra-system-shutdown service.
$ sudo systemctl enable canberra-system-shutdown.service
And go to reboot try it :)
or
$ /usr/bin/canberra-gtk-play --file="/usr/share/sounds/freedesktop/stereo/desktop-login.oga" --description="GNOME Login"
