foobar ekspert spørgsmål

Jeg har på et engelsk forum posted mit spørgsmål. Nu poster jeg det også her i håb om at der er nogle eksperter et sted derude :)

----------
Hello. I'm somewhat new to foobar. I was wondering if there is any way to make foobar change the master volume of the computer simultaniously as the volume of foobar is changed.

Hope you understand what i mean...

The reason why i ask is because i'm using foo_osd, and i would like to bind the volume buttons on my multimedia-keyboard to both "foobar volume control" so that i get the OSD volume indicator. But if i globalise the keybind to foobar, the keys suddendly dosn't work with the master volume anymore.
Therefore i would think it would be the easiest if foobar could control master volume simultaniously.

Thank you.
