Sound Theme doesnot work after fresh Installation of Opensolaris Build 99

After the crashed Update to Build 100a, I reinstalled Build 99. Some adjustments
had to be done, but the login-Sound was not audible anymore.
I tried to activate the ESD, but some messages told me, that ESD is not used
after some Build of Gnome it isn't used anymore.

So what I found was the autostart-things of gnome are in
/usr/share/gnome/autostart
There is also a file for the login which shows the command which plays the sound:
libcanberra-login-sound.desktop:

/usr/bin/canberra-gtk-play --id="desktop-login" --description="GNOME Login"
OnlyShowIn=GNOME;
Executing the command in the terminal responded that it didn't found any
sound file to play.

After some searching I had to install the package with the sound files:
# pkg install pkg:/SUNWxdg-sound-theme@0.5.11-0.99

After installing the commandline execution gave the login-Sound to the speakers.
