This is a minor problem, but some users might want to listen to a welcome tune after login to Fedora 12.
First, get a copy of desktop login tune (desktop-login.ogg) from Fedora 11. You can also download from here: desktop-login.ogg
Then copy this file to the folder /usr/share/sounds/freedesktop/stereo
Logout and login again, you should be able to hear the login tune after login.
If there is still no desktop login sound, select: System >> Preference >>Startup Applications
Ensure that the application “GNOME login sound” is check. Click edit and make sure that the command /usr/bin/canberra-gtk-play –id=”desktop-login” –description=”GNOME Login” is available.
Depends on the sound drivers and the sound system initiation procedure, some system may not be able to play the sound.
