using more than one audio output device at the same time

[dDaYb]

Hi, guys.
How is it possible to use both audio-out devices at the same time in vlc? In the way what one audio stream from avi goes to one output (hdmi in my example) and the other to the other (headphones).
the goal is that people wach movie in different languages.
Thank you in advance.

i'm using dell 1525 and it is ok on this device to have playing music in foobar via headphones and watching movie on hdmi plazma.
so as far as i can understand it is possible in theory...
