It works because by default you cannot raise the levels to damaging levels.
Lucky me, I noticed the thing when I read the source code. I would not
hear anything today if I would have been unlucky. I can hear the headphones
to the next room when they are at maximum.
It is not a lesson to learn. This is about safety. Why should people
learn about bad design by experimentation?

It may not add to your system. In my system it forbits any software
to alter volumes beyond __what I want__.
>Things are safe as they are right now.
You're welcome to my house and listen to my headphones when I turn
my SoundBlaster to its highest quality sound, to maximum S/N ratio.
(You won't care about S/N issues after that, ever, read about Tinnitus.)
