   I have already encountered and solved a similar problem in Fvwm2, not   
   XFCE.  Perhaps some of what I did will apply.  Here is the code I put   
   into my ~/.fvwm2rc file--the Fvwm2 configuration file:   
      
   # Mute   
   # Key F8        A       N       Exec :   
   Key XF86AudioMute       A       N       Exec :   
      
   # Volume down   
   Key F9  A       N       Exec /usr/local/bin/changevol down   
   Key XF86AudioLowerVolume        A       N       Exec /usr/local/bin/   
   changevol down   
      
   # Volume up   
   Key F10 A       N       Exec /usr/local/bin/changevol up   
   Key XF86AudioRaiseVolume        A       N       Exec /usr/local/bin/   
   changevol up   
      
   My purposes were different, as I turned off the mute capability.  Volume   
   up and down I treated by use of my own script /usr/local/bin/changevol--   
   let me know if you need the script.  I captured key presses of both the   
   built-in keys and F9 and F10, as some keyboards lack the built-in keys.   
      
   I hope this helps.
