How to include microphone adjustment in sound menu

When I use skype I have 2 scrollbars for the sound:

How can I keep those 2 scrollbars all the time, and not only when I have skype conversations? When I don't talk with skype, only speaker scrollbar is visible.

Edit1:

Here's an output of sudo updatedb; locate -r indicator-sound-service$:

1. Download build dependencies and source

   sudo apt-get build-dep indicator-sound
   apt-get source indicator-sound
   

2. Change src/volume-control.vala

   Modify default from false to true:

   /** true when a microphone is active **/
   public bool active_mic { get; private set; default = true; }
   

   Comment line that sets hiding variable using //:

               case Context.SubscriptionEventType.REMOVE:
                   //this.active_mic = false;
                   break;
   

3. Build and install

   cd indicator-sound-12.10.2+14.04.20140313/
   mkdir build
   cd build/
   cmake ..
   make
   sudo make install
   

4. Kill running indicator-sound-service or Logout/login

   pkill -f indicator-sound-service
   

Note:

For some reasons, you may want to skip sudo make install or didn't work, then just replace the executable:

sudo rm /usr/lib/x86_64-linux-gnu/indicator-sound/indicator-sound-service
sudo cp src/indicator-sound-service /usr/lib/x86_64-linux-gnu/indicator-sound/indicator-sound-service
pkill -f indicator-sound-service
