Is possible to amplify the system sound with software, without losing sound quality?I want it for videos and,especially,for listening to music. What programs for Ubuntu 12.04 can do this?

You can use the sound server PulseAudio Volume Control (aka. pavucontrol and previously known as Polypaudio):
- run on Ubuntu (KDE/Gnome)
- amplify the sound (default max boost: ~150%)
- however the higher the amplification, the more distorted the sound will be
FYI if you want to go over the default max boost (~150%): see this thread.
