Comment 6 for bug 285549

Solution is the libcanberra 0.10
I found this page: https://launchpad.net/~gkulyk/+archive with the latest libcanberra 0.10 (the one used in intrepid is outdated 0.6).
I included the line: "deb http://ppa.launchpad.net/gkulyk/ubuntu intrepid main" in synaptic and reloaded. Immediately the new 0.10 showed up as an upgrade, marked all upgrades, and rebooted.
WOW!! All the "Allerts and Sound Effects" working 100%!!
Just had to manually select some windows minimize/maximize sounds and everything is ok now!
Just one minor problem, the logout sound still not working, but I think it's related to another bug (https://bugs.launchpad.net/bugs/274124 ???).
Hope it helps!
Regards
