What -  did I read that right?
This card definitely has analog volume input control.
The 'Analog Volume' mixer tabs in Envy24 or Mudita24 control it.

BTW About the jumpers that control input level: There are undocumented 
 'in-between' jumper settings for the input level. (The jumpers just switch
 various resistors in or out.)
I discovered the settings and was forced to use them when the existing 
 choices of levels were not quite enough for me.
