presario 711ea hotkey support on mandriva 2005
 

I am trying to get the hotkeys on my presario 711ea working. It has got 6 hot keys : internet browser, mail program, search, and volume up/down.
If i press both volume up and down together it mutes the sound but it wont turn up or down.
I would like to get them all working if possible.

does anyone have an idea how i could do this?

thanks
