Curious... Today, the issue is gone. Now the login sound works perfectly. I don't know why, because I didn't touch anything. Maybe the rebooting solves the problem.
Sorry about the inconvenience. I close this bugreport now, and I'll open it if the problem reappears. ** Changed in: gnome-session (Ubuntu) Status: Needs Info => Rejected -- [Dapper] Login sound doesn't work after last update https://launchpad.net/bugs/43424 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
