No sound for non-admin users after 3/10 updates

After the updates (kb958690, kb905866, kb960225) were installed on the morning of 3/10, sound no longer functions on users that do not have admin privileges. If I log back into an admin account everything works fine. I've rolled back the Windows Mail (kb905866) update, but it has had no effect. Given that the other two are for security updates, I left those in place.

For other reference, I run a Sony VIAO media center that was working fine before that update. And after the update, there is one of the standard application services from Sony that is not prompting for an admin password when logging into a non-admin account. Entering the correct information has no effect.

Without rolling back security updates, or opening up all users as admin, are there any ideas on how to get the sound back?
