Same issue as described above by Yfrwlf. Upon reboot using Ubuntu 13.04 the volume is reset to 100% which causes blaring speaker volumes unless turned down to the previous level. This bug only started occurring for me after a fresh install of Ubuntu 13.04. Previously on a 12.10 install upgraded from 12.04 the issue did not happen.
