VLC setting volume from command line/bash

bash volume vlc

With the risk of feeling really really stupid here, but I seem not to be able to set the volume of VLC from command line??

vlc file.mp3 --vol 0

I have read the man pages as well as googled but I can not get the above to work. Also tried --volume 0, -vol 0, -volume 0 (as well as putting the volume option before the file name).

No matter, VLC starts with its preset volume. Using VLC 1.1.5 on Ubuntu. (I intend to use the line in a bash script therefore I can not use the VLC GUI) /J

Update

I have tried different values. I now run vlc with very verbose. This section looks a bit suspicious (but I have no idea how to interpret it!):

Seems to be a known bug. Volume option doesn't have any effect
