Sorry to ressurrect this, but I have the exact same problem as the original poster.
I am trying to record to Audacity via the front mic input on some viglen desktops, however this doesn't work unless a user with admin rights changes the record source in the Realtek control panel software from 'rear mic' to 'front mic'. Obviously I need a way to do this programatically rather than changing it manually on 150 machines.
I have tried using process monitor to capture what is being changed, but I can't really make sense of the output, and exporting then importing the entirety of the relevant key doesn't seem to work.
The registry key already posted by matt disables the front panel detection which takes care of one problem, but the record source settings seem to be stored somewhere else entirely.
