Public bug reported: I've been getting no sound from time to time when booting up. In Settings/Sound there is only a Dummy Output available. Looging out and in restores the internal and external speakers in the list but they still have no output. Rebooting usually solves the problem.
It started either yesterday (2 September 14) or the day before. I have both Ubuntu Trusty and Ubuntu Gnome Utopia installed in other partitions and neither have experienced the same bug.
