MOC Error - Ubu 9.10 with Sound settings.

Hello,
I found an error when i was setting sound level more than 100% [new option in Ubuntu 9.10 Gnome 2.28.1].
Error:

mocp: interface_elements.c:3436: iface_set_mixer_value: Assertion `value >= 0 && value <= 100' failed.
Aborted

What is setting the sound level to more than 100% supposed to do ? Is this for sound amplification ?
Which sound system are you using (ALSA, OSS, Jack) ?
MOC assumes 100% is the maximum you can get - I would believe this is a sane assumption; but then Ubuntu strikes again... :-P

Thanks for the report, fixed in SVN.
Hiben: it seems to be additional software volume boost.
