   Not sure, but maybe try  xmodmap -pk | grep Mute  to find the   
   appropriate keycode, which seems to be 121 for my keyboard   
   (but I'm not seeing anything that looks like "Unmute"; maybe   
   you're just supposed to press Mute a second time?). Anyway,   
   now use  xev  and press the key you think should be Mute,   
   and see if its displayed keycode actually is your Mute keycode.   
   Suppose it's not... suppose it's, say, 66, and from xmodmap   
   you know Mute should be 121. Then  xmodmap -e "keycode 66 = Mute"   
   should re-assign the key you want to be Mute so that it actually is.   
   Same idea for Unmute, I suppose, but like I said, I'm not seeing   
   any Unmute key for my keyboard.
