Public bug reported:
Exactly the same as issue as here -
http://askubuntu.com/questions/112123/how-do-i-maximize-the-sound-
volume-on-a-macbook-pro-in-gnome-shell
If I use the volume keys to set volume to 100%, the sound is very low. However,
if I open the Sound dialog, the "Output Volume" slider goes up to 150%, which
allows me to comfortably hear sound. Unfortunately, if I use the volume keys
thereafter, it practically mutes the sound again, and doesn't let me increase
the volume to 150% without first opening the Sound Settings dialog. I know how
to use System Settings to increase volume beyond 100%. What I want is for 100%
to actually be the true 100% so when I use the volume key to increase volume,
it doesn't decrease volume. e.g. If I set it to 150%, and then press the
"increase volume" key, the volume goes down to 100%.
