On both the machines where I run Gnome and have sound cards, the upgrade
from 6.0 to 6.1 caused the startup sound to stop playing. I have applied
the latest updates and have gnome-core-1.0.54-2, gnome-audio-1.0.0-7 and
Also, on logout, the shutdown sound plays as the logout dialog is
displayed, not as Gnome is exiting, which seems to me to be wrong.
Cannot reliably reproduce - long-term this will be fixed with the new GNOME
sound events system, but short-term I will just ignore it.
