Hey Marco, alan pope noticed that these short bursts happen when the CPU usage is at 100%. and the culprit seems to be the system settings app. There is already a bug about this in the system settings app that you can find at https://bugs.launchpad.net/ubuntu/+source/ubuntu-system-settings/+bug/1337200. I believe that is the cause of the short audio burst when the alarm goes of. With that I am closing this bug and request you to track the other bug for further updates.
